General Description
The ZSP4423 is a high voltage output DC-AC converter
that can operate from a +2.2V to +5.0V power supply. The
ZSP4423 is designed with our proprietary high voltage
BiCMOS technology and is capable of supplying up to
200V
PP
signals, making it ideal for driving small electrolu-
minescent lamps. The device features 10nA (typical)
standby current, for use in low power portable products.
An inductor is used to generate the high voltage, and an
external capacitor is used to select the oscillator fre-
quency. The ZSP4423 is offered in an 8-pin narrow SOIC
package or an 8-pin MSOP package. For delivery in die
form, please consult the factory.
