PRODUCT OVERVIEW

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

(±0.2%) and load (±0.5% and ±0.6%) regulated.

Each has an on/off control function, and the two

output voltages can be trimmed independently.

(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,

EN60950-1 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.

... Output Trimming Both the 5V and 3.3V outputs of the BCP Series can be independently trimmed via a trimpot (Figure 3A single fixed resistor as shown (Figures 3B & 3C). The trimpot can be used to determine the value of a single fixed resistor. A single fixed resistor can increase or decrease the output voltage depending on its connection. Fixed resistors should be metal-film types with absolute TCR’ ...
