SM8141 NIPPON PRECISION CIRCUITS INC. EL Sheet Driver OVERVIEW The SM8141 is a transformer-less electroluminescent (EL) sheet lamp driver, capable of driving sheets up to 50cm2 in size. It employs built-in high withstand voltage output MOS transistors and requires few external components, making it ideal for compact driver units in portable equipment.
