Description

The Supertex HV809 is an off-line high voltage EL lamp driver integrated circuit designed for driving EL lamps of up to 350nF at 400Hz. The input supply voltage can be a rectified nominal 120V AC source or any other DC source up to 200V. It will supply the EL lamp with an AC square wave with a peak-to-peak voltage of two times the input DC voltage.

The HV809 has two internal oscillators, a low output voltage linear regulator, and a high voltage output H-bridge. The high voltage output H-bridge frequency is set by an external resistor connected between the R EL-osc and GND pins. The EL lamp is connected between VA and VB. For the HV809 in the 8-pin package, an external RC network can be connected between the oscillator's osc1 and osc2 pins to pulse the EL lamp on and off.
