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).
