EL Sheet Driver
OVERVIEW
The SM8141 is a transformer-less electrolumines-
cent (EL) sheet lamp driver, capable of driving sheets
up to 50cm
2
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.
