D340B

Electroluminescent

Lamp Driver IC

General Description:

The Durel^®D340B Lamp Driver is part of a family of

high-voltage switch-mode IC drivers intended to reduce

cost, improve performance and simplify the design of EL

backlighting systems. A D340B IC with a single inductor

completes a low-cost circuit capable of driving up to 5

in²electroluminescent lamps.
