General Description

The Supertex HV826 is a high voltage driver designed for driving EL lamps. The input supply voltage range is from 1.8V to 3.5V. 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 ±80V. The chip can be enabled/disabled by connecting the resistor on RSW-OSC to VDD/ground.
