General Description
MC33441 General Description
The MC33441 is a DCAC 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 Hbridge network. The input supply voltage range is from 1.8V to 3.5V and is capable to supply a typical 140Vpp AC output voltage.
The standby current of the device is typically 10nA 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 8Pin TSSOP miniature package. The operating temperature is 20°C to 70°C.
