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 voltage 6.0VDC
Supply current ~170mA
Lamp size range Up 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).
