Description
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 a
opto-coupler. When FPO is low, the main SMPS is operational.
Remote On/Off logic input from CPU or main-board. The power supply will be turned on/off
after 38mS / 115mS delay.
12V over current protection sense input. Regarding typical application, this pin is
connected to the positive end of a current shunt through one resistor. When the voltage on
IS12 is higher than that of VS12 by 5mV, OCP will be enabled. One current sink, 8 x Iref, is
used to determine the voltage drop between the positive end of the current shunt and
VS12. Adjusting the value of the external resistor can adjust the threshold for OCP
accordingly. The operation for IS5 or IS33 is the same.
Reference setting. One external resistor Ri connected between RI and GND pin will
determine a reference current, Iref = 1.15/Ri, for OTP and OCP programming.
Over-temperature protection. Only valid for SG6513T.
An NTC thermistor is connected from RT pin to GND. At high temperature, the impedance
of the NTC will decrease and hence the voltage on RT will decrease. When the voltage on
RT pin is lower than 0.95V limit, the over-temperature protection will be enabled. The
internal pull high current source is equal to 5 x Iref.
5V over current protection sense input.
3.3V over current protection sense input.
12V over/under-voltage control sense input.
3.3V over/under-voltage control sense input.
