ZSP4422A
Electroluminescent Lamp Driver
General Description
The ZSP4422A is a high voltage output DC-AC converter
that can operate from a +2.2V to +5.0V power supply. The
ZSP4422A is designed with our proprietary high voltage
BiCMOS technology and is capable of supplying up to
160V_PP signals, making it ideal for driving small electrolu-
minescent lamps. The device features 50nA (typical)
standby current, for use in low power portable products.
One external inductor is required to generate the high
voltage, and an external capacitor is used to select the
oscillator frequency. The ZSP4422A is offered in an 8-pin
narrow SOIC package or an 8-pin MSOP package. For
delivery in die form, please consult the factory.
