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 2.0 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 the RSW-Osc and REL-Osc pins
to the VDD pin, and disabled when connected to GND.
The HV830 has two internal oscillators, a switching MOSFET
and a high-voltage EL lamp driver. The frequency of the
switching converter MOSFET is set by an external resistor
connected between the RSW-Osc and the VDD pins. The EL
lamp driver frequency is set by an external resistor connected
between the REL-Osc and the VDD pins. An external inductor
is connected between the LX and VDD pins. A 0.01µF to 0.1µF
capacitor is connected between the CS pin and the GND. The
EL lamp is connected between the VA and VB pins.
The switching MOSFET charges the external inductor and
discharges it into the CS capacitor. The voltage at CS will start
to increase. Once the voltage at CS reaches a nominal value
of 100V, the switching MOSFET is turned OFF to conserve
power. The output pins VA and VB are configured as an H-
bridge and are switched in opposite states to achieve 200V
peak-to-peak across the EL lamp.
