DESCRIPTION
The SP4423 is a high
voltage output DC-AC converter that can operate from a 2.
2V-6.
0V power supply.
The SP4423 is capable of supplying up to 200 VPP signals, making it ideal for driving 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.
