Function
Transconductance voltage error amplifier output.
Transconductance current error amplifier output.
Current sense input to the PFC current limit comparator.
PFC gain modulator reference input.
Input for RMS line voltage compensation.
Connection for oscillator frequency setting components.
Input to the high speed zero voltage crossing comparator.
Analog signal ground.
Return for the PFC and ZVS driver outputs.
ZVS MOSFET driver output.
PFC MOSFET driver output.
Shunt-regulated supply voltage.
Buffered output for the internal 7.5V reference.
Transconductance voltage error amplifier input.
Absolute Maximum Ratings
Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum rat-
ings are stress ratings only and functional device operation is not implied.
