PFC transconductance current error amplifier output
PFC gain control reference input. Before the chip wakes up,
IAC is connected to VCC. After the chip wakes up, IAC is
connected to AGC.
Current sense input to the PFC current limit comparator
Input for PFC RMS line voltage compensation
Connection point for the PWM soft start capacitor
PWM voltage feedback input
Oscillator timing node; timing set by RT CT
When in current mode, this pin functions as the current sense
input; when in voltage mode, it is the PWM input from PFC
output (feed forward ramp).
PWM current limit comparator input
