Bel Power DC/DC converters supply up to 40 watts

The Bel Power division of Bel Fuse Inc. has launched the SRSB-40U series of isolated DC/DC converters for high-speed networking, telecommunications, and computing applications. 

The 1/16 brick (1.3 x 0.9-inch footprint) parts are capable of delivering up to 40 W of output power at higher voltages, or up to 18 A of output current at an output of 1.2 V.

The SRSB-40U DC/DC converters are designed to operate efficiently over a 4:1 input range of 18 to 75 Vdc for use on boards with industry-standard bus voltages of 24 V, 48 V or 60 V. The ultra-wide input range permits the use of single power system designs which are capable of operating in a variety of environments. The series is RoHS 6/6 compliant, and carries a full set of international safety approvals including UL, UL60950, and IEC/EN60950.

The open frame construction of the SRSB-40U Series, combined with its wide input voltage range and footprint of less than 1.2-square inches, makes it suitable for use in a variety of telecommunications, networking, wireless and industrial designs requiring tight inter-board spacing. Applications include mobile/optical switches, high capacity network routers, high-end datacommunications and medical systems, as well as in a variety of systems using distributed power architecture.

The DC/DC converters offer fixed frequency synchronous rectification control for high efficiency, together with positive/negative remote sense, remote on/off logic, and ±10% output trim. Protection features include input and output over-voltage protection, over-temperature protection, current limit and short circuit protection, and under-voltage lockout.

The parts are available in both surface-mount and through-hole designs, and in seven distinct output voltages ranging from 1.2 V to 12 V. They are provided with either active-high or active-low on/off polarity. Modules operate over an ambient temperature range of -40° to +85°C.
