INNOVATION and EXCELLENCE

Dual Output

Mixed Voltage, BWR Models

5V and 3.3V, Independent Dual Output

30 Watt, DC/DC Converters

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 1ꢀ load and 0.5ꢀ

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 88ꢀ 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

prevent asynchronously generated beat frequencies.

Features

Independently regulated 5V/3.3V outputs

5V @ 3A/3.3V @ 4.25A simultaneously

delivered

Independent V^OUTTrim pins for margining

Independent On/Off Control pins

88% efﬁciency; 75mV ripple/noise

Input ranges: 10-18V, 18-36V or 36-75V

UL 1950 and EN60950 safety approvals

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 shutdown. A Sync

option is available in place of 3.3V on/off control. These devices meet IEC950,

UL1950 and EN6950 safety standards. CB reports are available upon request.

"D48A" models are CE marked (meet LVD requirements).
