SM8141
EL Sheet Driver
OVERVIEW
The SM8141 is a transformer-less electrolumines-
cent (EL) sheet lamp driver, capable of driving sheets
up to 50cm2 in size. It employs built-in high with-
stand voltage output MOS transistors and requires
few external components, making it ideal for com-
pact driver units in portable equipment.
FEATURES
s Dedicated EL driver
s 50cm2 maximum EL sheet drive capability
s Noise-less smooth drive waveform
s Two oscillators (EL and coil)(SM8141A)
s Stand-by function (SM8141B)
s High-efficiency MOS transistor driver
s Dual supply operation possible
(See TYPICAL APPLICATIONS)
s 2.0 to 5.5V supply operation
s 200Vp-p maximum drive voltage
s 250Hz standard drive frequency
s 8-pinVSOP package
s Chip form
