Data Sheet

D372A

Electroluminescent

Lamp Driver IC

General Description:

The Durel® D372A is designed to drive EL lamps with a regulated

high-voltage signal. This driver IC uses a proprietary circuit design

for programmable wave-shaping for low-noise performance in

applications that are sensitive to audible and electrical noise, such

as cellular phones and handsets.

MSOP-10
