(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.

I_AC

100

PFC Current Sense: for both Gain Modulator and PFC

ILIMIT comparator.

I_SENSE

-1.2

0.7

Line Input Sense pin and also, it is the brown out sense

pin.

V_RMS

VCC+0.3

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.
