Product Summary

The ZSP4403LEU is a high voltage output DC-AC converter that can operate from a +2.2V to +5.0V power supply. The ZSP4403LEU is designed with our proprietary high voltage BiCMOS technology and is capable of supplying up to 160VPP signals, making it ideal for driving small electroluminescent lamps. The device features 50nA (typical) standby current, for use in low power portable products.
One external inductor is required to generate the high voltage, and an external capacitor is used to select the oscillator frequency. The ZSP4403LEU is offered in an 8-pin narrow SOIC package or an 8-pin MSOP package. For delivery in die form, please consult the factory. The applications of the ZSP4403LEU include PDAs, Cellular phones, Remote controls, Handheld computers.
