EL Driver

The SM8144B is a transformer-less electroluminescent (EL) driver IC, capable of driving Displays up to 70 cm2 in size. It is a high-efciency driver that features revised inductor switching Transistor ON resistance and output circuit conguration to reduce loss, all in a compact package. A Microcontroller Interface pin (ENA) is provided, which CAN be used to control the EL driver ON/OFF function. The device is available in 8-pin VSOP packages. By Nippon Precision Circuits Inc, (NPC)
