HV850 Datasheet (Supertex) - Inductorless EL Lamp Driver

HV850, Inductorless EL Lamp Driver

The Supertex HV850 is a high voltage electroluminescent (EL) Lamp Driver IC.

It is designed to drive EL lamps of up to 1.5in2, with capacitive values up to 5.0nF.

The HV850 converts a low voltage DC input to a high voltage AC output across an EL lamp.

It uses a charge pump scheme to boost the input
