SM8142 NIPPON PRECISION CIRCUITS INC. EL Sheet Driver OVERVIEW The SM8142 is a transformer-less electroluminescent (EL) sheet lamp driver, capable of driving sheets up to 30 cm2 in size. It employs a high-efciency driver output circuit conguration to control power dissipation. It is available in ultra-small 8-pin SON (Small Outline Non-leaded) packages*, making possible the construction of small, thin, low-power driver units. * : SM8142×D FEATURES I I I I I I I I I I I I Dedicated EL driver Noise-less smooth drive waveform High-efciency output circuit Two oscillator circuits built-in (SM8142A) Stand-by function (SM8142B) Stable temperature characteristics Ultra-small package 1.6 to 5.5 V supply voltage 0.3 mA typ.
