The SP4427 is a high voltage output DC-AC converter that can operate from a single 1.5 Vdc battery supply. The SP4427 is capable of supplying up to 250 Vpp signals, making it ideal for driving electroluminescent lamps. The device features 100nA (typ) standby current, for use in low power portable products. One external inductor is required to generate the high voltage charge, and two external capacitors are used to select the oscillator and lamp frequencies. The SP4427 is offered in both an 8 pin narrow SOIC or micro SOIC package. For delivery in die form, please consult the factory.
