DESCRIPTION…
The SP4426 is a high voltage output DC-AC converter that can operate from a 2.2V-6.0V power supply. The SP4426 is capable of supplying up to 300 Vpp signals, making it ideal for driving electroluminescent lamps. The device features 100 nA (typ) standby current, for use in low power portable products. One external inductor is required to generate the high voltage charge, and one external capacitor is used to select the oscillator and Lamp frequencies. The SP4426 is offered in a 14 pin narrow SOIC. For delivery in die form, please consult the factory.
