Analog Devices, Inc.  today announced the Power by Linear™ LTM4661, a low power step-up µModule^® regulator in a 6.25mm x 6.25mm x 2.42mm BGA package. Only a few capacitors and one resistor are required to complete the design, and the solution occupies less than 1cm² single-sided or 0.5cm² on double-sided PCBs. The LTM4661 incorporates a switching DC/DC controller, MOSFETs, inductors and supporting components. The LTM4661 operates from a 1.8V to 5.5V input supply, and continues to operate down to 0.7V after start-up. The output voltage can be set by a single resistor ranging from 2.5V to 15V. The combination of the small, thin package and wide input and output voltage range is ideal for a wide range of applications including optical modules, battery-powered equipment, battery-based backup systems, bias voltage for power amps or laser diodes and small DC motors.

• View the LTM4661 product page, download data sheet, order samples and evaluation boards: http://www.analog.com/LTM4661

The LTM4661 can deliver 4A continuously under 3.3VIN to 5VOUT, and 0.7A continuously under 3.3VIN to 12VOUT.

Visitors to Analog Devices’ (ADI) stand at the forthcoming European Microwave Week 2018 (Madrid, Spain, September 25 – 29) will be able to view demonstrations and exhibits that reaffirm the company’s position as the foremost semiconductor supplier for RF, microwave and millimeter wave designs at every frequency from DC to over 100 GHz.

ADI’s stand (#135) at EuMW2018 will host the first public demonstration of several significant products released to the market in recent weeks, advancing the state-of-the-art in areas such as 5G communications, phased-array RADAR and software-configurable radio.

5G transceivers handle legacy radio standards

With its award-winning RadioVerse wideband transceivers, Analog Devices transformed the design process for the RF path in a multitude of radio products. The ADI stand at EuMW will feature the latest generation of RadioVerse chip which increases bandwidth, adds further integration and cuts power demand. The IC anticipates the upcoming need for large numbers of 5G base stations to be deployed economically; with twice the bandwidth – 200 MHz – of its predecessor and tunability over 75 MHz to 6 GHz, it will support not only 5G RF standards, but also 2G, 3G and 4G. Replacing up to 20 components and more-than-halving power demand, a demonstration of this IC will show configurable RF capability that extends beyond 5G, to a broad range of infrastructure, aerospace and defense systems.

12-bit, 10-GSPS ADCs further boost bandwidths

In analog-to-digital conversion, ADI has brought to market many successive generations of high-speed products, each time advancing performance across their specifications. To be demonstrated at EuMW, ADI’s latest 12-bit, 10.25-GSPS ADC targets next-generation communications, defense and test and measurement applications. Extended parametric performance offers greater Nyquist bandwidth supporting digitization of RF signals up to 7 GHz. The demonstration will highlight the device’s faster sampling (factor of 2.5x), improved dynamic range and superior noise performance over similar devices.

Cutting size, weight, power in phased-array RADAR

As RADAR deployments become more diverse, applications encounter limits of SWaP – size, weight and power. Phased-array RADARs are attractive for their flat-panel, no-moving-parts attributes, but demand efficient transmit/receive performance over many channels. Highlighting a newly-released device, a demonstration on the ADI stand at EuMW18 will show how integration can resolve this dilemma; analog beamforming will be shown in a system that will track visitors as they approach the exhibit. Simplifying the designers’ task, this 4-channel chip replaces multiple conventional components to build TDD RADARs operating in X and Ku bands, integrating T/R switching and providing complete support for phase-control on a per-channel basis.

High integration in a leading-edge PLL chip

The PLL (phase-locked-loop) and VCO (voltage-controlled oscillator) functions are fundamental to RF designs, more so in an increasingly digital signal-handling context. Also seen for the first time on the ADI stand at EuMW18, will be a synthesizer IC comprising a PLL with fully integrated VCO, as well as on-chip low-dropout regulators (LDOs) to provide the necessary highly stable supply rails; plus integrated tracking filter technology. The demonstration will show how the lowest levels of RMS jitter can be achieved at high output frequencies, in applications that will span aerospace and defense, test & measurement, and communications infrastructure.

Analog Devices’ applications engineers will be on hand at stand #135 to answer visitors’ questions on any aspect of RF signal chain design, building on ADI’s decades of experience at both component and system level.

NORWOOD, MA – August 16, 2018 – Analog Devices  announces the Power by Linear™ ADP5138, automotive qualified, high efficiency, 3.2MHz synchronous quad output buck regulators, incorporating a unique fixed frequency, peak current mode, PWM control architecture that reduces conducted and radiated emissions. The device’s high efficiency buck regulators improve thermal management, operate down to 0.8V outputs and deliver up to 1A of continuous output current from each channel. Also integrated is a 250mA low output noise (20µV_RMS from 10Hz to 100kHz), high PSRR (61dB at 1kHz) low dropout linear regulator (LDO) for powering noise-sensitive devices. This high level of integration and combination of features, in addition to the compact 4mm x 4mm LFCSP package, make it ideal for automotive, industrial and instrumentation systems, as well as DC to DC point-of-load applications where space is at a premium.

• View the ADP5138 product page, download the data sheet, order samples and evaluation boards: http://www.analog.com/ADP5138

The ADP5138 runs at a fixed PWM switching frequency of 3.2MHz, or can be synchronized to the external clock from 2.8MHz to 3.5MHz, which is outside the amplitude modulation (AM) band. Furthermore, this high switching frequency reduces the size of external components, enabling a smaller solution footprint. The four buck regulators run 90° out-of-phase to each other, reducing the input ripple current and the input capacitor size and lowering the system’s electromagnetic interference (EMI). Integrated internal compensation simplifies design, and the device’s internal soft-start circuitry and power-up sequencing reduce input inrush current. The ADP5138 monitors the input voltage and provides input overvoltage lockout (OVLO), undervoltage monitor (UVM), and undervoltage lockout (UVLO) features. The device also monitors the undervoltage and overvoltage of the outputs. The power-on reset (POR) signal is asserted when the input or output voltage fault occurs.  Additional protection includes overcurrent protection (OCP) and thermal shutdown (TSD).

The ADP5138 and the automotive qualified version, the ADP5138W, are offered in a low profile (0.75mm), compact 28-lead 4mm x 4mm LFCSP package with backside exposed metal pad for excellent thermal performance.

The precision resistors, which are integrated in LTC6363-0.5, LTC6363-1 and LTC6363-2, have been designed with overall system performance in mind, striking a balance between noise and linearity, and utilizing laser trimmed factory calibration to achieve a level of precision which is difficult and costly to achieve discretely.  Initial gain accuracy is 45ppm maximum and varies by only 0.5ppm/^oC maximum over temperature.  Common mode rejection ratio, which is typically limited by discrete resistor matching, is an outstanding 94dB minimum, equivalent to a 0.002% resistor matching.

“One of the challenges when driving high performance SAR ADCs is finding an appropriate driver that consumes comparable power while maintaining the noise and linearity performance of the ADC.  This is where the LTC6363 family excels.  For example, the LTC2378-20 20-bit SAR ADC consumes 21mW at 1Msps,” says Maziar Tavakoli, Design Manager, Linear Products and Solutions.  “The LTC6363 family’s noise and linearity have negligible impact on ADC performance while consuming a mere 19mW, comparable to the ADC’s power consumption.  Now with the LTC6363-0.5, LTC6363-1 and LTC6363-2 you can get this same ADC driving performance plus the added precision afforded by the precision integrated resistors, all in the same compact MSOP8 package.”

The entire LTC6363 family operates with supply voltages from 2.8V (±1.4V) to 11V (±5.5V) while drawing 1.75mA typical supply current. The devices are specified for operation over a temperature range from –40°C to 125°C.  The LTC6363 fixed-gain series are available in a 3mm x 5mm plastic MSOP8 package, and the LTC6363 (without resistors) is also offered in the tiny 2mm x 3mm DFN package.  For more information, visit http://www.analog.com/LTC6363.

NORWOOD, MA – August 10, 2018 – Analog Devices  announces the Power by Linear™  LTC4041, a complete supercapacitor backup power management system for 2.9V to 5.5V supply rails that must be kept active during a main power failure.  Supercapacitors have higher power density than batteries, making them ideal for systems requiring high peak power backup for short periods of time.

• View the LTC4041 product page, download data sheet, order samples and evaluation boards: http://www.analog.com/LTC4041

The LTC4041 uses an on-chip bidirectional synchronous converter to provide high efficiency step-down supercapacitor charging, as well as high current, high efficiency boost backup power. When external power is available, the device operates as a step-down battery charger for one or two supercapacitor cells while giving preference to the system load.  When the input supply drops below the adjustable power-fail input (PFI) threshold, the LTC4041 switches to step-up regulator operation, capable of delivering up to 2.5A to the system load from the supercapacitor. During a power fail event, the device’s PowerPath™ control provides reverse blocking and a seamless switchover from input power to backup power. Typical applications for the LTC4041 include ride-through “dying gasp” supplies, high current ride-through 3V-5V uninterruptible power supplies (UPSs), power meters, industrial alarms, servers and solid-state drives.

The LTC4041 includes an optional overvoltage protection (OVP) function using an external FET which can protect the IC from input voltages greater than 60V. An internal supercapacitor balancing circuit maintains equal voltages across each supercapacitor and limits the maximum voltage of each supercapacitor to a predetermined value. Its adjustable input current limit function enables operation from a current limited source while prioritizing system load current over battery charge current.  An external disconnect switch isolates the primary input supply from the system during backup. The device also includes input current monitoring, an input power fail indicator, and a system power fail indicator.

The LTC4041 is offered in a low profile (0.75mm) 24-lead 4mm x 5mm QFN package with backside metal pad for excellent thermal performance. The device operates from –40°C to 125°C, in both E and I grades. For more information, visit http://www.analog.com/LTC4041.

NORWOOD, MA – August 08, 2018 – Analog Devices  announces the Power by Linear™ LTC7862, a high efficiency switching surge stopper with overvoltage and overcurrent protection for high availability systems. The LTC7862 drives an N-channel power MOSFET stage. During normal operation the LTC7862 passes the input voltage through to the output with minimal conduction loss. When an input overvoltage condition occurs, the LTC7862 starts switching as a high efficiency DC/DC regulator, protecting critical downstream components by limiting the output voltage and current.

• View the LTC7862 product page, download data sheet, order samples and evaluation boards: http://www.analog.com/LTC7862

The LTC7862 builds on popular linear surge stoppers such as the LTC4363 by offering high efficiency switching protection to extend output current capability and reduce power loss during transients and faults. Supply voltages surge when the load current changes abruptly in long inductive power busses. The situation is aggravated in automotive applications by the energy stored in the alternator’s inductance, causing an elevated and extended voltage surge during a load dump. The power handling capability of a surge stopper is limited by the power lost in the protection circuit. In a linear surge stopper, the power capability is determined by the size of the pass MOSFET, while in a switching surge stopper the power capability is determined by conversion efficiency. Due to its lower power loss, a switching surge stopper can operate through longer input voltage surges at higher output current than a linear solution.

The LTC7862 has an input voltage operating range of 4V to 140V, 150V abs max. An external fault timer capacitor configures the limited time spent in overvoltage mode and keeps the switching surge stopper below a safe peak operating temperature when power loss is at its highest levels. The fault timer saves system cost and size by allowing component selection to be optimized for normal mode rather than overvoltage transient and fault conditions. 

In MIL-STD-1275 applications the LTC7862 protects devices operating from a 28V vehicle power bus, where this bus voltage can reach as high as 100V and last up to 500ms. The LTC7862 also fits into industrial, avionics, and automotive power, including ISO 7637. 

The LTC7862 is available in 20-Lead 4mm × 5mm QFN and TSSOP packages. Three temperature grades are available, with operation from –40 to 125°C for the extended and industrial grades and a high temp automotive grade of –40°C to 150°C. For more information, visit www.analog.com/LTC7862.

• Download EVWSS firmware by submitting a request to  http://www.analog.com/srf.  Please specify EVWSS.2.0.0 in the additional comments field in the software request form.

The ADI solution includes a complete hardware and firmware reference design. It can be scaled for high performance with the ADSP-BF706 or entry level applications with the ADAU1450 Digital Audio Processor. The ADSP-BF706 can also be used to create in-cabin engine sound to contribute to an improved driving experience for vehicle owners. The ADSP-BF706 uses memory mapped quad SPI memory providing faster and simpler access to the stored audio files used to create the engine sound. It can access up to 24 WAV files simultaneously, compared to conventional products that can typically access only five.

NORWOOD, MA – January 29, 2018 – Analog Devices announces the Power by Linear™ LTC7815, a high frequency (up to 2.25MHz) triple output (buck, buck, boost), synchronous DC/DC controller that maintains all output voltages in regulation during automotive cold crank conditions. A 12V automotive battery can droop to less than 4 volts during engine restart or cold crank, causing reset of infotainment systems and other electronics that operate from 5 volts and higher. The high efficiency synchronous boost converter feeds the two step-down converters, avoiding output voltage dropout when the car battery voltage droops, a useful feature in automotive start/stop systems that shut off the engine at idle to save fuel. Alternatively, the buck controllers can be powered from the input for a general-purpose triple output controller. 

• View the LTC7815 product page, download data sheet, order samples and evaluation boards: www.linear.com/product/LTC7815

The LTC7815 operates from an input voltage of 4.5V to 38V during start-up and maintains operation down to 2.5V after start-up. The synchronous boost converter can produce output voltages up to 60V and can run with the synchronous switch fully ON at 100% duty cycle to pass through the input voltage when it is high to reduce noise and maximize efficiency. The two step-down converters can produce output voltages from 0.8V to 24V with the entire system achieving efficiency as high as 95%. Its low 45ns minimum on-time enables high step-down conversions while switching at 2MHz, avoiding critical noise-sensitive frequency bands such as AM radio and allows for smaller external components.

The LTC7815 can be configured for Burst Mode^® operation, reducing quiescent current to 28μA per channel (38μA for all three on) while regulating the output voltage at no load, a useful feature for preserving battery run times in always-on systems. The powerful 1.1Ω onboard all N-channel MOSFET gate drivers minimize switching losses and provide output current of more than 10 amps per channel, limited only by external components. Furthermore, the output current for each converter is sensed by monitoring the voltage drop across the inductor (DCR) or by using a separate sense resistor. The LTC7815’s constant frequency current mode architecture enables a selectable frequency from 320kHz to 2.25MHz or it can be synchronized to an external clock over the same range.

Additional features include an onboard LDO for IC power and gate drive, output voltage tracking or adjustable soft-start, a power good signal and an external V_CC input. The reference voltage accuracy is ±1% over a –40°C to 125°C operating temperature range.

The LTC7815 is available in a 38-lead 5mm x 7mm QFN package.  Two temperature grades are available, with operation from –40 to 125°C for the extended and industrial grades and a high temperature automotive range of –40°C to 150°C. For more information, visit www.linear.com/product/LTC7815.
