鈼廌escription
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-adjusting
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.
鈼廇pplications
Power supplies for copiers, personal computers,
facsimiles, AV equipment, measuring instruments,
vending machines, security device, registers,
industrial equipment, and maintenance tools
