Description

The SM8143A is a transformer-less electroluminescent (EL) driver IC, capable of driving displays up to 80 cm2 in size. It is a high-efficiency driver that features revised coil switching transistor ON resistance and output circuit configuration to reduce loss.

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. SM8143A is available in 16-pin VSOP packages.
