Product Summary
The SP4425CU-724-1 is a high voltage output DC-AC converter that can operate from a single 1.5 VDC power supply. The SP4425CU-724-1 is capable of supplying up to 220 VPP signals, making it ideal for driving electroluminescent lamps. The device features 1 mA (typical) 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 SP4425CU-724-1 is offered in both an 8-pin narrow SOIC and 8-pin micro SOIC package. For delivery in die form, please consult the factory. Applications are (1)Pagers; (2)Digital watches; (3)Backlit LCD displays.
