SM8143A
EL Driver
OVERVIEW
The SM8143A is a transformer-less electroluminescent (EL) driver IC, capable of driving displays up to
80cm2 (SM8143AV) or 70cm2 (SM8143AD) in size. It is a high-efï¬ciency driver that features revised coil
switching transistor ON resistance and output circuit conï¬guration to reduce loss. The EL drive frequency and
coil drive frequency can be controlled independently, making the driver circuit optimizable to match applica-
tion requirements. A microcontroller interface pin (ENA) is provided, which can be used to control the EL
driver ON/OFF function.
