General Description:
The Durel® D355A 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.
