DC/DC converter

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-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 1) Wide range of input voltage. 2) High power conversion efficiency. 3) Built-in output ON / OFF switch. 4) Applicable to various purposes by fine-adjusting the output
voltage. 5) Small number of external components required. 6) Heat sink unnecessary. 7) Compact package. BP5220A / BP5221A / BP5222A : SIP9
