General Description
The Supertex HV830 is a high-voltage driver designed for driving
EL lamps of up to 50nF. EL lamps greater than 50nF can be
driven for applications not requiring high brightness. The input
supply voltage range is from 2.0V to 9.5V. The device uses a
single inductor and a minimum number of passive components.
The nominal regulated output voltage that is applied to the EL
lamp is ±100V. The chip can be enabled by connecting the
resistors on R
connected to GND.
The HV830 has two internal oscillators, a switching MOSFET,
and a high-voltage EL lamp driver. The frequency for the switch-
ing converter MOSFET is set by an external resistor connected
between the R
driver frequency is set by an external resistor connected be-
tween R

The switching MOSFET charges the external inductor and
discharges it into the C
increase. Once the voltage at C
100V, the switching MOSFET is turned OFF to conserve power.
The outputs V
switched in opposite states to achieve 200V peak-to-peak across
