SM8141

EL Sheet Driver

OVERVIEW

The SM8141 is a transformer-less electrolumines-

cent (EL) sheet lamp driver, capable of driving sheets

up to 50cm2 in size. It employs built-in high with-

stand voltage output MOS transistors and requires

few external components, making it ideal for com-

pact driver units in portable equipment.
