 ZSP4423 -- Electroluminescent Lamp Driver for Low Power Applications

The ZSP4423 is a high voltage output DC-AC converter that can operate from a +2.2V to +5.0V power supply. The ZSP4423 is designed with our proprietary high voltage BiCMOS technology and is capable of supplying up to 200Vpp signals, making it ideal for driving small electroluminescent lamps. The device features 10nA (typical) standby current, for use in low power portable products. An inductor is used to generate the high voltage, and an external capacitor is used to select the oscillator frequency. The ZSP4423 is offered in an 8-pin narrow SOIC package or an 8-pin MSOP package. For delivery in die form, please consult the factory.


  • +2.2V to +5.0V battery operation

  • High voltage output typical 160Vpp
  • Internal oscillator
Target Applications:
  • PDAs
  • MP3 players
