... OVERVIEW The SM8143A is a transformer-less electroluminescent (EL) driver IC, capable of driving displays 80cm (SM8143AV) or 70cm (SM8143AD) in size 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 applica- tion requirements ...
