Design for High Efficient Power Supply at both Full Load and Light Load
PFC transconductance current error amplifier output
(Gmi).
IAC has 2 functions:
1. PFC gain modulator reference input.
2. At start up, IAC is connected to VCC and it helps to
reduce the startup time and it helps to reduce the no
load consumption. 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; can use it to on/off the boost
follower function; it is pulled down by 300 ohm internal
resistor when DCILIMIT reach 1V; the power is limited
during the PWM Brown out.
