 ZSP4412A -- Electroluminescent Lamp Driver with Super Low Standby Current

The ZSP4412A is a high voltage output DC-AC converter that can operate from a +2.2V to +3.6V power supply. The ZSP4412A is designed with our proprietary high voltage BiCMOS technology and is capable of supplying up to 250VPP 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 oscillator is needed as a clock source. The ZSP4412A 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 +3.6V battery operation
  • 50nA maximum standby current (10nA typical)
  • High voltage output typical 160Vpp
  • External oscillator required
  • Enable control pin
Target Applications:
  • Watches
  • Pagers
  • Backlit LCD displays
