Description

Dimensions (Unit : mm)

The BP5275 series of DC/DC converters utilize high rated

voltage.

2xC0.5

A control circuit, switching element, and coil are built in, along

with input/output capacitors, resulting in stable operation with

no external components required.

6.2 MAX.

16.3 MAX.

C0.5

High conversion efficiency, combined with an original heat

dissipation structure, enables configuration an ultra-compact

switching power supplies.

500mA output is possible with no heat sink required (800mA

with heat sink).

In addition, the ICs are pin-compatible with conventional

TO-220 LDO regulators, making replacement easy.

Low ripple voltage with high precision output ensure stable

operation against the fluctuating voltages from main power

supplies, making them ideal for use as local power supplies

(i.e. for microcontrollers).
