PIN FUNCTION DESCRIPTION

Pin

Symbol

Description

1, 2

N/C

No connection.

3

SIGGND

Ground reference pin for control circuits. This should be connected to power ground on the PCB.

4

COMP

The feedback and compensation network of the linear regulator are connected to this pin.

5

VCC

Input power to chip. There is an internal clamp at 15 V to allow for a shunt regulator circuit on this pin for

high voltage inputs.

6

VREG

This is the regulated output of the internal linear regulator.

7

DRIVE

Output drive of oscillator, that drives external diode/capacitor network.

8

PWRGND

Ground reference pin for driver current.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values

(not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage

may occur and reliability may be affected.

1. Above this voltage, a series resistor is necessary to limit current into the shunt regulator.
