PRODUCT OVERVIEW

Murata Power Solutions' BWR series of DC/DC con-

verters now includes two independent converters in

one 2" x 2" package. The BWR-5/3-3.3/4.25 family

provides both 5V at 3 Amps and 3.3V at 4.25 Amps

for a combined output power of 30 Watts from input

ranges of 10V to 18V (-D12A), 18 to 36V (-D24A), or

36 to 75V (-D48A).

to provide ±1% load and ±0.5% line regulation.

Individual trim pins and a negative or positive

on/off control pin allow independent adjustment of

output voltages and any combination of power-on

sequencing between the 5V and 3.3V outputs. A

high efficiency of 88% allows full load operation

Each output is regulated by its own control loop
