EST7502B
EST7502B is PC Power Supply PWM manufactured by EST.
DESCRIPTION
The EST7502B 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 (PGO), Remote On/Off control and etc. It can minimize external ponents of switching power supply systems in personal puter.
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.
