General Description

The Supertex HV852DB1 demoboard contains all necessary

circuitry to demonstrate the features of the HV852 EL lamp

driver.

Simply connect it to a power supply and a lamp, as shown

below. For additional assistance in implementation of the

HV852 circuit, please refer to the HV852 data sheet.

Board Layout and Connection Diagram

Connections:

EN - Enable Input

Enables/Disables the lamp driver. Logic high (VDD), enables

the driver, and a logic low (GND), disables the driver. This

input may be connected to a mechanical switch, or to a logic

circuit output.

Supplies the HV852 EL driver IC. The supplied circuit is

optimized for 2.4 to 5.0V operation.

Connects to an EL lamp. Polarity is irrelevant.

GND - Circuit Ground

Connect to V
