Description

COMP

This pin is the error amplifier output and is made available for loop compensation.

This is the inverting input of the error amplifier. It is normally connected to the

switching power supply output through a resistor divider.

A voltage proportional to the inductor current is connected to this input. The PWM

uses this information to terminate the output switch conduction.

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

500 kHz is possible.

GROUND This pin is the ground reference of the device.

6OUTPUT

This output directly drives the gate of a power MOSFET. Peak currents up to 1 A

are sourced and sunk by this pin.

This pin is the positive supply of the control IC.
