General Description

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.
