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 compact driver units in portable equipment.
