DESCRIPTION  
The SP4428 is a high voltage output DC-AC converter that can operate from a single 1.5 VDC  
powersupply. TheSP4428 iscapableofsupplying200VPP (typical), makingitidealfordriving  
electroluminescent lamps. The device 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  
applications using LCDs in dim or low light environments. The SP4428 is offered in an 8-pin  
narrow SOIC. For delivery in die form, please consult the factory.
