The SM8144B is a transformer-less EL (Electro Luminescence) driver IC, capable of driving displays up to 70cm2 in size. It is a high-efficiency driver that features revised inductor switching transistor ON resistance and output circuit configuration to reduce loss, all in a compact package. It is available in small VSOP-8 package, making possible the compact driver units in portable equipment. A microcontroller interface pin (ENA) is provided, which can be used to control the EL driver ON/OFF function.
