Application Note
HV857 EL Lamp Driver Circuits
This application note presents six EL driver circuits utilizing
the Supertex HV857 integrated circuit. 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.
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. Excessive
input current may be a good indication of connection errors
or incorrect component values. A sharp rise in current usually
indicates a saturated inductor. To avoid inductor saturation,
use a higher current rated inductor or increase the conversion
frequency by lowering the RSW resistor value.
