comparator of the Master PFC control loop. The Power
MOSFET current is sensed by a resistor and the resulting
voltage needs to be filtered and it can be applied to this pin.
Its maximum threshold is about 500mV.
Its threshold is determined by the PFC multiplier output
current and it is a sine wave current.
Isense Master designed for cycle by cycle current shaping
and cycle by cycle current limit. It also determines when the
Isense Slave to turn off.
The Input pin of the Slave PFCCMP which is current sense
comparator of the Slave PFC control loop. The Power
MOSFET current is sensed by a resistor and the resulting
voltage needs to be filtered and it can be applied to this pin.
Its maximum threshold is about 500mV.
Its threshold is determined by the PFC multiplier output
current and it is a sine wave current.
Ground
Slave PFC driver output; It can drive Power MOSFET and
IGBT with 30 ohm pulled up and 15 ohm pulled down.
Master PFC driver output; It can drive Power MOSFET and
IGBT with 30 ohm pulled up and 15 ohm pulled down.
Supply voltage:
It has a 50mA 16.5V shunt regulator.
1% Precision 7.5V Reference Pin and it sources maximum 3
mA
PFC transconductance voltage error amplifier input; it also
senses PFCOVP when VFB is greater than 2.75V and it also
turns off PFC when VFB is less than 0.5V. It is also the
Tri-Fault Protection input.
