DATEL's BWR series of DC/DC converters now includes two independent con-
verters 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 independent, both outputs are driven from synchronized PWMs to pre-
vent asynchronously generated beat frequencies.
Housed in a plastic case, all models include input Pi filtering, input overvolt-
age protection, independent output short circuit and current limiting protection and
independent output overvoltage protection as well as thermal shutdown. These
devices meet IEC950, UL1950 and EN6950 safety standards. CB reports are avail-
able upon request. "D48A" models are CE marked (meet LVD requirements).
