BM1P10CFJ
PWM Controller IC for AC/DC Converter

The PWM Controller for AC/DC power supplies provides an optimal system for all products that include an electrical outlet. It realizes the high flexibility in power supply design with external switching MOSFET and current detection resistor. This IC can make efficiency high because it has functions such as AC low voltage protection and X capacitor discharge and operates frequency reduction and burst operation at light load. In addition, this IC also has a built-in power save function and it reduces electric power at no load. This IC has following various protection functions.
