Data Sheet  
Non-Isolated Step-Down 3-Terminal DC/DC Converters  
BP5275-18 / BP5275-25 / BP5275-33 / BP5275-50  
Dimensions (Unit : mm)  
Description  
The BP5275 series of DC/DC converters utilize a synchronous  
rectification system.  
A control circuit, switching element, and coil are built in, along  
with input/output capacitors, resulting in stable operation with  
no external components required.  
5.2  
13.8 MAX  
2xC0.5  
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).  
0.75

2.54 0.2  
0.5  
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).

Note : Dimensions without tolerance is typical.  
Applications  
Power supplies for copiers, personal computers,  
facsimiles, AV equipment, measuring instruments,  
vending machines, security device, registers,  
industrial equipment, and maintenance tools  
Features  
1) No external parts required  
2) High power conversion efficiency.  
3) Heat sink unnecessary.  
4) Low output ripple voltage  
5) High output voltage accuracy  
6) Pin-compatible with conventional 3-pin LDOs  
7) Compact package.
