Step-down DC/DC Converters(Non-isolated)

BP5220A / BP5221A / BP5222A

The BP5220A, BP5221A, BP5222A, are DC / DC

converters that use a pulse width modulation (PWM)

system. They contain control circuits, switching devices,

rectifiers, and coils, and operate by only connecting an

I / O smoothing capacitor. With a high efficiency of power

conversion, the modules are available in stand-alone

9-pin SIP packages with no heat sink required.

They can be applied to various purposes by fine-tuning

the output voltage and switching on and off. With a wide

range of input voltage, the modules are best suited for

obtaining a stable local power supply from a main

power supply with a large voltage variation.

Power supplies for copiers, personal computers,

facsimiles, AV equipment, measuring instruments,

vending machines, security device, registers,

industrial equipment, and maintenance tools

1) Wide input voltage range

2) High power conversion efficiency.

3) Built-in output ON / OFF switch.

4) Adjustable output voltage ensures wide compatibility

5) Few external components required.

6) Heat sink unnecessary.

7) Compact package.

... BP5220A/BP5221A/BP5222A Operation notes (1) No circuit is installed in the modules to protect against excessive output currents. Therefore, take physical safety measures such as using a fuse if short-circuit loading is probable. (2) The output current should be reduced according to an increase in the input voltage or ambient temperature. Use the modules within the derating curve range. ...
