General Description:
The Durel® D355B Lamp Driver is part of a family of switch-
mode IC drivers intended to reduce EL system cost, improve
performance and to simplify the design, specification, and
manufacture of EL backlighting systems. This driver is intended
to provide adequate power for most watches, data banks and
cellular phone backlighting applications.
