The SP6641 is an ultra-low quiescent current, high efficiency, DC-DC boost converter designed
for single and dual cell alkaline, or Li-ion battery applications found in PDA’s, MP3 players, and
other handheld portable devices. The SP6641 features a 10mA quiescent current, a 0.3W Nchannel
charging switch, 0.9V input startup, and a 0.33A or 1.0A inductor current limiting feature.
The SP6641 is offered in a 5 pin SOT-23 package and provides an extremely small power supply
footprint optimized for portable applications. The SP6641 is preset to 3.3V and can be controlled
by a 1nA active LOW shutdown pin.
