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. Applications Description 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 6) Heat sink unnecessary. 7) Compact package.
