Description
1
IEAO
PFC transconductance current error amplifier output
2
IAC
PFC gain control reference input
3
ISENSE
Current sense input to the PFC current limit comparator
4
VRMS
Input for PFC RMS line voltage compensation
5

PWM voltage feedback input
7
RAMP1 (RtCt)
Oscillator timing node; timing set by RT, CT
8
RAMP2 (PWM RAMP)
In current mode, this pin functions as the current-sense input. In voltage mode,
it is the PWM input from the PFC output (feed forward ramp).
