PIN FUNCTION DESCRIPTION
Pin
Symbol
Description
1, 2, 8
PWRGND
Ground reference pin for driver current.
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 30 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.
MAXIMUM RATINGS (Maximum ratings are those, that, if exceeded, may cause damage to the device. Electrical Characteristics are not
guaranteed over this range.)
