PRODUCT OVERVIEW

Murata Power Solutions' BCP "half-brick" series

has expanded to include dual-output, 3.3V and

2.5V DC/DC converters. The BCP-3.3/15-2.5/15-

D24 (18-36V input) and BCP-3.3/15-2.5/15-D48

(36-75V input) are fully isolated DC/DC convert-

ers housed in standard "half-brick" packages

(2.3" x 2.4" x 0.5"). These BCP’s can support

any combination of 3.3V and 2.5V loading up to

a combined total of 15 Amps. Both outputs are

fully isolated (1500Vdc) and independently line

(±0.2%) and load (±0.5%) regulated.

and negative logic versions available), and both

output voltages can be trimmed independently.

efﬁ ciency of 84% and are fully speciﬁ ed 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 UL1950 and IEC/EN60950-1 safety

standards, including BASIC insulation require-

ments. CB reports are available on request. "D48"

models are CE marked (meet the requirements

of LVD).
