2 GENEAL DESCIPTION WT7522 Data Sheet ev The WT7522 is a pulse width modulation (PWM) control circuit with complete 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), emote On/Off control, Opamp and etc. It can minimize external components of switching power supply systems in personal computer. Over Voltage Protection (OVP) monitors 3.3V, 5V, 12V and PT input voltage level. Under Voltage Protection (UVP) monitors 3.3V, 5V, 12V and one negative voltage input voltage level. Power Good Output monitors the voltage level of power supply.
