Overview
® SP4425 Electroluminescent Lamp Driver Low Voltage Applications s Low Voltage, Single Battery Operation (VBATTERY > 1.
1 VDC) s DC to AC Inverter for EL Backlit Display Panels s Externally Adjustable Internal Oscillator s Low Current Standby Mode APPLICATIONS s Pagers s Digital Watches s Backlit LCD Displays DESCRIPTION The SP4425 is a high voltage output DC-AC converter that can operate from a single 1.
5 VDC power supply.
The SP4425 is capable of supplying up to 220 VPP signals, making it ideal for driving electroluminescent lamps.
The device features 1 µA (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 SP4425 is offered in both an 8-pin narrow SOIC and 8-pin micro SOIC package.
For delivery in die form, please consult the factory.
