General Description
The Supertex HV829A/B are high
voltage EL lamp driver integrated circuits designed for driving EL lamps of up to 70nF at 1000Hz.
The input supply
voltage range is from 2.
7V to 5.
5V.
These devices use a single inductor, a high
voltage switching FET and a minimum number of passive components.
The HV829A/B will supply the EL lamp with an AC square wa...
