DESCRIPTION

The SP4425Q is a high voltage output DC-AC converter that can operate from a single 3.0

V_DCpower supply. The SP4425Q is capable of supplying up to 220 V_PPsignals, making it ideal

for driving electroluminescent lamps. The device features 100 nA (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 select the oscillator and lamp

frequencies. The SP4425Q is offered in an 8-pin µSOIC package. For delivery in die form,

please consult the factory.
