IAC
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.

SS
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.
