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 requirements. 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 load-
ing 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
fi nish, 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 fi ltering, input overvoltage and
undervoltage shutdown circuitry, output overvolt-
age protection, output short-circuit and current
limiting protection, and thermal shutdown.
Each design also provides trim capability and
on/off control function. Fully synchronous output
rectifi cation renders high effi ciency and no-load
operation.
BWR power sharing modules offer low ripple
and noise performance, high effi ciency (88%),
1500Vdc of isolation voltage, and are fully
specifi ed for –40 to +100°C operation. These
devices meet IEC950, UL1950 and EN6950 safety
standards, including BASIC insulation require-
ments for “D48” models. CB reports are available
on request. “D48” models are CE marked (meet
LVD requirements).
