Features

General Description

❏ Processed with HVCMOS^®technology

❏ Input voltage up to 200V DC

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. The HV809 will

supply the EL lamp with an AC square wave with a peak-to-peak

voltage of two times the input DC voltage.

❏ 400V peak-to-peak output voltage

❏ Output load up to 350nF (100 in²for 3.5nF/in²lamp)

❏ Adjustable output lamp frequency

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-oscand GND pins. The EL lamp is

connected between V_Aand V_B. 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.

❏ Adjustable On/Off pulsing frequency
