SP4423

Electroluminescent Lamp Driver

Low Power Applications

DESCRIPTION

The SP4423 is a high voltage output DC-AC converter that can operate from a 2.2V-6.0V

power supply. The SP4423 is capable of supplying up to 200 V

driving electroluminescent 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 frequency. The SP4423 is offered in

an 8-pin narrow SOIC and 8-pin

µSOIC packages. For delivery in die form, please consult

the factory.
