Description
PFC transconductance current error amplifier output
(Gmi).
IAC has 2 functions:
1. PFC gain modulator reference input.
2. Typical RAC resistor is about 6 Mega ohm to sense
the line.
PFC Current Sense: for both Gain Modulator and PFC
ILIMIT comparator.
Line Input Sense pin and also, it is the brown out sense
pin.
Soft start capacitor pin; it is pulled down by 70K ohm
internal resistor when DCILIMIT reach 1V; the power is
limited during the PWM Brown out.
