SP4424 - Electroluminescent Lamp Driver Dual Oscillators

General Description

The SP4424 is a high voltage output DC-AC converter that can operate from a single battery supply voltage as low as 2.2V.

The SP4424 is capable of supplying up to 220 VPP signals, making it ideal for driving electroluminescent lamps.

Key Features

  • 5µA (maximum) standby current, for use in low power portable products. An inductor is used to generate high voltage pulses, and two external capacitors are used to select the inductor and the lamp oscillator frequencies. The SP4424 is offered in both an 8-pin narrow SOIC and 8-pin micro SOIC packages. For delivery in die form, please consult the factory.
