SP4428 - Electroluminescent Lamp Driver High Drive Capability for Low Voltage Applications

General Description

The SP4428 is a high voltage output DC-AC converter that can operate from a single 1.5 VDC power supply.

The SP4428 is capable of supplying 200 VPP (typical), making it ideal for driving electroluminescent lamps.

Key Features

  • 1µA (typical) standby current, for use in low power portable products. One external inductor is required to generate the high voltage charge, and one external capacitor is used to produce a clock signal that generates the coil and lamp frequencies. The SP4428 is ideal for PDAs, pagers, and other low power portable.
