1 / 9 page © Semiconductor Components Industries, LLC, 2006 July, 2006 − Rev. 3 1 Publication Order Number: MC33441/D MC33441 Electroluminescent Lamp Driver IC The MC33441 is a DC−AC inverter integrated circuit for driving EL lamps. It can boost the supply voltage to the level required by EL lamps and also provide high voltage AC lamp excitation. It consists of an oscillator, a frequency divider, a coil driving circuit and a switched H−bridge network. The input supply voltage range is from 1.8 V to 3.5 V and is capable to supply a typical 140 Vpp AC output voltage. The standby current of the device is typically 10 nA which is ideal for low power portable products. Externally, one inductor and one resistor are needed to generate the desirable voltage charge and to fine tune the oscillator’s frequency. This device is offered in 8−Pin TSSOP miniature package. The operating temperature is −20°C to 70°C.
