WT7522 Overview
The WT7522 is a pulse width modulation (PWM) control circuit with plete protection circuits for used in the SMPS (Switched Mode Power Supply). It contains various functions, which are Over Voltage Protection, Under Voltage Protection, Power Good Output (PG), Remote On/Off control, Opamp and etc. It can minimize external ponents of switching power supply systems in personal puter.
