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’s 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’s 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 (±0.2%) and load (±0.5% and ±0.6%) regulated.
Both BCP models feature input pi ﬁlters, input undervoltage and overvoltage
shutdown, input reverse-polarity protection, output overvoltage protection, current
limiting, and thermal shutdown. Each has an on/off control function, or an optional
sync capability and the two output voltages can be trimmed independently.
BCP Model DC/DC’s deliver low noise (50mVp-p), high efﬁciency (87%) and are
fully speciﬁed for –40 to +100°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).
