SP6648 Overview
The SP6648 is an ultra-low quiescent current, high efficiency step-up DC-DC converter ideal for single cell, dual cell alkaline and Li-Ion battery applications such as digital still cameras, PDA’s, MP3 players, and other portable devices. The SP6648 bines the high delivery associated with PWM control, and the low quiescent current and excellent light-load efficiency of PFM control.
