General Description
The Supertex HV857LDB1 demoboard contains all
necessary circuitry to demonstrate the features of the
HV857L EL lamp driver.
Simply connect it to a power supply and a lamp. For
additional assistance in designing EL driver circuits,
please refer to application notes AN-H33 (effect of
external components on performance of Supertex
EL drivers).
Board Layout and Connection Diagram
Low Noise, High Voltage
EL Lamp Driver IC Demoboard
Connections:
EN - Enable Input
Enables/Disables the lamp driver. A logic high, (connect
to VDD) enables the driver and a logic low, (connect to
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.
VDD - IC Supply
Supplies the HV857L EL driver IC. The supplied circuit is
optimized for 3.0V operation. The operating range can be
from 1.8 to 5.0V. Connect to the positive terminal of a power
supply.
VIN - Inductor Supply
Supplies the high voltage power converter. Connect to the
positive terminal of a power supply.
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 required.
VA and VB - Lamp Connections
Connect to an EL lamp. Polarity is irrelevant.
Note:
Make sure all the above connections are made before powering up the supply voltages.
