ROHM BP51L12, BP51L05 Datasheet
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 connected. 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 .
Absolute maximum ratings
3) Heat sink unnecessary.
4) Compact SIP 9-pin package.
