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).

Each output is regulated by its own control loop

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

up to +65°C ambient temperature in a still air

environment. Although functionally indepen-

dent, both outputs are driven from synchronized

PWMs to prevent asynchronously generated beat

frequencies.

Housed in a plastic case, all models include

input Pi ﬁltering, input overvoltage protection,

independent output short circuit and current

limiting protection and independent output

overvoltage protection as well as thermal shut-

down. These devices meet IEC950, UL1950 and

EN6950-1 safety standards. CB reports are avail-

able upon request. "D48A" models are CE marked

(meet LVD requirements).
