BP51L12 datasheet pdf

321 Regulator ICs DC / DC converter unit BP51L05 / BP51L12 The BP51L05 and BP51L12 are DC / DC converter units that use a pulse width modulation (PWM) system. They contain built-in control circuits, switching devices, rectifiers, and coils, and operate if only an I / O smoothing capacitor is con- nected. With a wide range of input voltage, the ICs are best suited for obtaining a stable local power source from a main power supply with a large voltage variation.
Applications Power supplies for copiers, personal computers, word processors, industrial equipment, and maintenance tools
Features 1) Wide range of input voltage. 2) High power conversion efficiency. 3) Heat sink unnecessary. 4) Compact SIP 9-pin package.
