BCP Models
Dual Output, Mixed Voltage, Isolated 5V & 3.3 V,
"Half-Brick" 75 W DC/DC Converters
FEATURES
PRODUCT OVERVIEW
nꢀIndependent 5V and 3.3V outputs
nꢀEach output fully regulated
nꢀNo minimum load requirements
nꢀUp to 15 Amps per output
As your new, mixed-logic (5V and 3.3V) design
evolves and your current requirements change,
your new DC/DC converter will not. Murata Power
Solutions' 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
( 0.2ꢀ) and load ( 0.5ꢀ and 0.6ꢀ) 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, and the two
output voltages can be trimmed independently.
BCP Model DC/DC’s deliver low noise
(50mVp-p), high efficiency (87ꢀ) 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,
EN60950-1 and VDE safety standards, includ-
ing BASIC insulation requirements. CB reports
are available on request. "D48" models are CE
marked (meet the requirements of LVD). Selected
models are available with RoHS-6 hazardous
substance compliance.
