2 IAC PFC gain control reference input 0 1 mA
3 ISENSE Current sense input to the PFC current limit comparator -5 0.7 V
4 VRMS Input for PFC RMS line voltage compensation 0 6 V
5 SS Connection point for the PWM soft start capacitor 0 8 V
6 VDC PWM voltage feedback input 0 8 V
7 RAMP 1
(RTCT)
Oscillator timing node; timing set by RT CT 1.2 3.9 V
8 RAMP 2
(PWM RAMP)
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).
