... Remote Controls Handheld Computers 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 V 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 ...
