The BP5220, BP5221, BP5222, BP5220X, BP5221X, and BP5222X 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.
Applications
Power supplies for copiers, personal computers, facsimiles, AV equipment, measuring instruments, vending
machines, security device, registers, industrial equipment, and maintenance tools
Features
