Description

1

INV

Inverting input of the error amplifier.

2

COMP

Output of Error amplifier. The compensation network is placed between INV and

COMP pin.

3

MULT

Main input of the multiplier. Connected to the rectified main voltage via a resistor

divider and provides the sinusoidal reference to the current loop.

4

CS

Current sense input and one input of internal PWM comparator.

5

ZCD

Zero Current Detection input. A negative edge triggers MOSFET’ turn on.

6

GND

Ground.

7

GD

Gate driver output.

8

VCC

Supply voltage input.
