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.
