GENERAL DESCRIPTION
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), Remote 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.
