Data Sheet
Non-Isolated Step-Down 3-Terminal DC/DC Converters
BP5277-33 / BP5277-50 / BP5277-90 / BP5277-12 / BP5277-13 / BP5277-15
Description
The BP5275 series of DC/DC converters utilize high rated
voltage.
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
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).
