MC33441/D
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 1.8V 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 8–Pin TSSOP
miniature package. The operating temperature is –20
°
C to 70
°
C.
