Description
The BP5275 series of DC/DC converters utilize high rated
voltage.
Dimensions (Unit : mm)
A control circuit, switching element, and coil are built in, along

with input/output capacitors, resulting in stable operation with
no external components required.
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
