PIN FUNCTIONS

N.

Name

Fun ction

1

INV

Inverting input of the error amplifier. A resistive divider is connected between output regulated

voltage and this point, to provide the 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 multipler 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.

6

GND

Ground of the control section.

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).

Supply voltage of driver and control circuits.
