EL Sheet Driver
OVERVIEW
The SM8143A is a transformer-less electroluminescent (EL) driver IC, capable of driving displays up to 80
cm
in size. It is a high-efficiency driver that features revised coil switching transistor ON resistance and output
circuit configuration to reduce loss.
2
The EL drive frequency and coil drive frequency can be controlled independently, making the driver circuit
optimizable to match application requirements. A microcontroller interface pin (ENA) is provided, which can
be used to control the EL driver ON/OFF function. The device is available in 16-pin VSOP packages.
