Unit
8 Isense Master The Input pin of the Master PFCCMP which is current sense
0
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.

9 Isense Slave The Input pin of the Slave PFCCMP which is current sense
0
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
