Function
1
INV
Inverting input of the error amplifier. A resistive divider is connected between the output
regulated voltage and this point, to provide voltage feedback.
2
COMP
Output of error amplifier. A feedback compensation network is placed between this pin and the
INV pin.
3
MULT
Input of the multiplier stage. A resistive divider connects to this pin the rectified mains. A voltage
signal, proportional to the rectified mains, appears on this pin.
4
CS
Input to the comparator of the control loop. The current is sensed by a resistor and the resulting
voltage is applied to this pin.
5
ZCD
Zero current detection input. If it is connected to GND, the device is disabled.
6
GND
Current return for driver and control circuits.
7
GD
Gate driver output. A push pull output stage is able to drive the Power MOS with peak current of
400mA (source and sink).
8VCC
Supply voltage of driver and control circuits.
