Features

For your moderate-power mixed-logic designs, DATEL’s BMP-5/5-3.3/4-D24
(18-36V input) and BMP-5/5-3.3/4-D48 (36-75V input) are fully isolated DC/DC
converters providing both 5V and 3.3V outputs. Housed in DATEL’s standard 2" x 3"
x 0.5" metal packages, these BMP duals can simultaneously source up to 4.7 Amps
from their 5V outputs and up to 3.5 Amps from their 3.3V outputs. Both outputs are
fully isolated (1500Vdc) and independently line (±1.0%) and load (±1.0%) regulated.

Both models feature input pi fi lters, input overvoltage shutdown, input reverse­polarity protection, output overvoltage protection, output current limiting, and thermal
shutdown. Both outputs are controlled via the On/Off Control function (pin 5). The
5 Volt output can be adjusted ±5%.

BMP Model DC/DC’s deliver high effi ciency (82%) and are fully specifi ed for
–40 to +100°C operation. Their corrosion-resistant metal cases have non-conductive
baseplates and threaded inserts for easy heat-sink attachment and/or pcb mounting.
These devices satisfy IEC950, UL1950 and EN60950 safety requirements for BASIC
insulation. CE marking is available for "D48" models.

BMP 35 Watt DC/DC's are designed so an On/Off Control function

with positive polarity (no suffi x) or a Sync function ("S" suffi x) can be

added in the pin 5 position.
