As your new, mixed-logic (5V and 3.3V) design evolves and your current require-
ments change, your new DC/DC converter will not. DATEL鈥檚 BCP-5/15-3.3/15-D24
(18-36V input) and BCP-5/15-3.3/15-D48 (36-75V input) are fully isolated DC/DC
converters providing both 5V and 3.3V outputs. Housed in standard "half-brick"
packages (2.3" x 2.4" x 0.525"), the BCP鈥檚 can support any combination of 5V and
3.3V loading up to a combined total of 15 Amps. Both outputs are fully isolated
(1500Vdc) and independently line (鹵0.2%) and load (鹵0.5% and 鹵0.6%) regulated.
Both BCP models feature input pi 鏗乴ters, input undervoltage and overvoltage shut-
down, input reverse-polarity protection, output overvoltage protection, current limiting,
and thermal shutdown. Each has an on/off control function, and the two output volt-
ages can be trimmed independently.
BCP Model DC/DC鈥檚 deliver low noise (50mVp-p), high ef鏗乧iency (87%) and are
fully speci鏗乪d for 鈥?0 to +100擄C operation. Utilization of metal baseplate technology
with threaded inserts permits easy heat-sink attachment and/or pcb mounting. These
devices meet IEC950, UL1950, EN60950 and VDE safety standards, including
BASIC insulation requirements. CB reports are available on request. "D48" models
are CE marked (meet the requirements of LVD).
