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, PDAs,
MP3 players, and other portable devices. The SP6648 combines the high-load efficiency
associated with PWM control, with the low quiescent current and excellent light-load efficiency
of PFM control. The SP6648 features 12μA quiescent current, synchronous rectification, a 0.3Ω
charging switch, anti-ringing inductor switch, programmable low-battery detect, under-voltage
lockout and programmable inductor peak current. The device can be controlled by a 1nA active
LOW shutdown pin.
