HV858 Datasheet (Supertex) - Tri-EL Lamp Driver IC

HV858, Tri-EL Lamp Driver IC

The Supertex HV858 is a high voltage triple EL lamp driver designed for driving combined EL lamps of up to 3.0 in2 (1.0 in2 each).

The input supply voltage range is from 1.8V to 6.5V.

The device is designed such that the input voltage to the inductor can be different from the input voltage to the de
