DESCRIPTION鈥?/div>
The
SP4426
is a high voltage output DC-AC converter that can operate from a 2.2V-6.0V
power supply. The
SP4426
is capable of supplying up to 300 Vpp signals, making it ideal for
driving electroluminescent lamps. The device features 100 nA (typ) 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 select the oscillator and Lamp frequencies. The
SP4426
is offered in a 14 pin narrow SOIC. For delivery in die form, please consult the factory.
