Application Note
HV823 & HV825
EL Lamp Driver Circuits
This application note presents fourteen EL driver circuits
utilizing the Supertex HV823 and HV825 drivers. They have
been optimized for a variety of applications and may be used
as-is or used as a starting point in designing a circuit for a
particular application.
When constructing and testing one of the driver circuits listed
below, keep in mind that results may differ from those given
due to component tolerances and lamp characteristics. For
the HV823, a 1.0nF capacitor from pin 2 to GND is needed
when a 0.01µF CS capacitor is used.
When making component changes, always remove supply
voltage rst. After making adjustments, bring up the supply
voltage slowly starting from the minimum required device
input voltage while monitoring input current. A sharp rise in
current usually indicates a saturated inductor. Use a higher
current rated inductor, a higher value inductor, or increase
conversion frequency by lowering RSW.
