GENERAL DESCRIPTION
The WT7520 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 (PGO), Remote On/Off control 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 and 12V input voltage level. Power Good Output monitors the voltage
level of power supply.
