FN4871 Product details

Description

3V3 (Pin 7) Connect this pin to the ATX 3.3V output.This pin provides the output current for the 2V5CLK pin, and is monitored for power quality.event, this pin is used to report the fault condition by being pulled to 5VSB.SS (Pin 16) Connect this pin to a small ceramic capacitor (no less than 5nF; 0.1µF recommended).The internal soft-start (SS) current source along with the external capacitor creates a voltage ramp used to control the ramp-up of the output voltages.Pulling this pin low wi
