SP4427
Electroluminescent Lamp Driver
Dual Oscillators with High Drive Capability
DESCRIPTION…
The
SP4427
is a high voltage output DC-AC converter that can operate from a single 1.5 Vdc
battery supply. The
SP4427
is capable of supplying up to 250 Vpp signals, making it ideal for
driving electroluminescent lamps. The device features 100nA (typ) standby current, for use
in low power portable products. One external inductor is required to generate the high voltage
charge, and two external capacitors are used to select the oscillator and lamp frequencies.
The
SP4427
is offered in both an 8 pin narrow SOIC or micro SOIC package. For delivery
in die form, please consult the factory.
