For applications requiring 33 Watts of power from 5V and 3.3V, DATEL offers a

new power sharing DC/DC converter capable of meeting your output current require-

ments. The BWR-5/6-3.3/7-D48 (36-75V input), BWR-5/6-3.3/7-D24 (18-36V input)

and BWR-5/6-3.3/7-D12 (10-18V input) are fully isolated DC/DC converters capable

of delivering any combination of 5V and 3.3V loading up to a combined total of 33

Watts of output power.

Housed in a standard 2" x 2" x 0.45" metal package coated with electrically non-

conductive finish, these converters utilize a shared control-loop system to assure load

regulation of ±1% for 3.3V output and ±1.5% for 5V output. All models include input

Pi filtering, input overvoltage and undervoltage shutdown circuitry, output overvoltage

protection, output short-circuit and current limiting protection, and thermal shutdown.

Each design also provides trim capability and on/off control function. Fully synchro-

nous output rectification renders high efficiency and no-load operation.

BWR power sharing modules offer low ripple and noise performance, high

efficiency (88%), 1500Vdc of isolation voltage, and are fully specified for –40

to +100°C operation. These devices meet IEC950, UL1950 and EN6950 safety

standards, including BASIC insulation requirements for "D48" models. CB reports

are available on request. "D48" models are CE marked (meet LVD requirements).
