EL Sheet Driver
OVERVIEW
The SM8142 is a transformer-less electroluminescent (EL) sheet lamp driver, capable of driving sheets up to
30 cm
2
in size. It employs a high-efficiency driver output circuit configuration to control power dissipation. It
is available in ultra-small 8-pin SON (Small Outline Non-leaded) packages*, making possible the construction
of small, thin, low-power driver units.
