UV&OC Protection
Power Good Input. For ATX SMPS, it detects AC line voltage through the
main transformer.
Ground
Fault Protection Output. Output signal to control the primary PWM IC through
an opto-coupler. When FPOB is low, the PWM IC is enabled.
Remote On/Off logic input from CPU or main-board. The power supply will
be turned on/off after 38mS delay.
12V
Reference setting. One external resistor Ri connected between RI and GND
pin will determine a reference current, I
12V over/under voltage protection.
5V over current protection.
3.3V over current protection
12V over/under voltage protection.

5V over/under voltage protection.
Power supply.
Power good logic output, 0 or 1(open-drain). Power good=1 means that the
power supply is good for operation. The power good delay is 300mS.
