PIN FUNCTIONS

Pin #

Name Description

1

GND Ground. Power return and reference node.

2

LINE UV/OV Set Point. Short to ground to turn the controller off.

3

FB

Regulation Feedback Input. Inverting input of the error amplifier. The non-inverting is internally

connected to 1.2V

4

COMP Error Amplifier Output.

5

RT

Oscillator Resistor and Synchronous Clock Pin. Connect an external resistor to GND for

oscillator frequency setting. It can be used as a synchronous input from external oscillator clock.

6

VCC

Supply Bias Voltage. A capacitor no less than 1uF is recommended to connect between GND.

7

VIN

High Voltage Startup Circuit Supply.

8

SW

Output Switching Node. High voltage power N-Channel MOSFET drain output. The internal

start bias current is supplied from this pin.
