The HV825DB1 EL Driver demoboard contains all the circuitry
necessary to drive an EL (Electroluminescent) lamp. Simply
connect it to a power supply and a lamp as shown below.
The supplied circuit has been optimized to drive a 1.5in2
lamp from a 1.5V supply. The circuit may be customized with
different component values to suit a particular application. For
additional assitance in designing EL driver circuits, please refer
to Application Notes AN-H33 (EL Lamp Driver Circuits)
and .AN-H34 (HV823 & HV825 EL Lamp Driver Circuits)

Parameter Value
Supply voltage 1.5V
Supply current 27mA (typical)
Lamp size range 1.5in2
Lamp frequency 450Hz (typical)
Converter frequency 30KHz (typical)
Connections:
EN - Enable Input
Enables/disables the lamp driver. A logic high (VDD) enables
the driver and a logic low (GND) disables the driver. This
input may be connected to a mechanical switch as shown,
or to a logic circuit output that has a source impedance of
less than 20kΩ.
VDD - IC Supply
Supplies the HV825 EL driver IC. The supplied circuit is op-
timized for 1.5V operation. Current draw is less than 1.0µA
when disabled.
VIN
- Inductor Supply
Supplies the high voltage power converter. Current draw is
approximately 27mA.
GND - Circuit Ground
Connect to VDD and VIN negative terminals. Supply bypass
capacitors for both VDD and VIN are provided on the demo
board. External supply bypass capacitors are not neces-
sary.
VA and VB - Lamp Connections
Connect to EL lamp of 1.5in2. Polarity is irrelevant.
