Function

1

COMP

This pin is the Error Amplifier output and is made available for loop compensation.

2

FB

The inverting input of the Error Amplifier. It is normally connected to the switching power

supply output through an external resistor divider.

3

CS

It is used either for current sense (normal mode) or skip cycle level selection (standby mode).

The oscillator frequency and maximum output duty cycle are programmed by connecting

5

GND

The ground pin.

6

OUTPUT

This output directly drives the gate of a power MOSFET. Peak currents up to 1.0 A are

sourced and sunk by this pin.

7

VCC

The power supply pin.
