Introduction

AI Translation

The Supertex HV857 is a high voltage driver designed for driving Electroluminescent (EL) lamps of up to 5.0 square inches. The input supply voltage range is from 1.8 to 5.0V. 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 ±95V. The chip can be enabled/disabled by connecting the resistor on RSW - Osc to VDD/GND.
