General Description
The Supertex HV859DB1 demoboard contains all the
necessary circuitry needed to demonstrate the features of
the HV859 EL lamp driver.
Simply connect it to a power supply and an EL lamp. For
additional assistance in designing EL driver circuits, please
refer to application notes AN-H33 (the effect of external
components on performance of Supertex EL drivers)
and AN-H43 (EL lamp driver circuits to reduce audible
lamp noise).
Board Layout and Connection Diagram
Connections:
EN - Enable Input
Enables/Disables the lamp driver. A logic high (connect
to V
GND), disables the driver. This input can be connected to
a mechanical switch, or to a logic circuit output that has a
source impedance of less than 20kΩ.
V
Supplies the HV859 EL driver IC. The supplied circuit is
optimized for 3.0V operation. The operating range can be
from 1.8V to 5.0V. Connect to the positive terminal of a
power supply.
