DESCRIPTION

The SP4422A is a high voltage output DC-AC converter that can operate from a 2.2V-5.0V power supply. The SP4422A is capable of supplying up to 220 VPP signals, making it ideal for driving electroluminescent lamps. The device features 50 nA (typical) standby current, for use in low power portable products. One external inductor is required to generate the high voltage, and one external capacitor is used to select the oscillator frequency. The SP4422A is offered in an 8-pin narrow and 8-pin micro SOIC packages. For delivery in die form, please consult the factory.
