General Description

The HV809DB2 EL Driver demoboard contains all the

circuitry necessary to drive an EL (Electroluminescent)

lamp. Simply connect it to a 4.5 to 6.0V DC supply and an

EL lamp as shown below.

For additional assistance in designing EL driver circuits,

please refer to application note AN-H36 (EL Lamp Driver

Circuits).

Board Layout and Connections

EL Driver Demoboard

Specications

Supply voltage6.0VDC

Supply current~170mA

Lamp size rangeUp to 12.5in2

Lamp frequency~200Hz

Connections:

V+ and V-

DC input supply voltage. V+ is the positive side of the sup-

ply and V- is the return side. It supplies the boost converter

circuit to generate the high DC voltage to the HV809. The

supplied circuit is optimized for an operating range of 4.5 to

6.0 volts.

VA and VB

VA and VB are the EL lamp connections. Polarity is irrel-

evant. Maximum lamp size should be limited to 12.5in2.

Switch

An On/Off slide switch is provided. When in the off position,

it disconnects the input voltage to the circuit.

Note:

The differences in brightness in the above measurements are due to the

differences between lamps used (it is within the tolerance of the lamp for

most manufacturers).
