Step-down DC/DC Converters(Non-isolated)
BP5220A / BP5221A / BP5222A
Description
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.
Applications
Power supplies for copiers, personal computers,
facsimiles, AV equipment, measuring instruments,
vending machines, security device, registers,
industrial equipment, and maintenance tools
Features
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.
