SP7648 -Ultra-low Quiescent Current, High Efficiency Boost RegulatorThe SP7648 is an ultra-low quiescent current, high efficiency Step-up DC-DC Converter ideal for
single cell Li-Ion or dual cell alkaline battery applications to drive various LEDs The SP7648
combines low quiescent current and excellent light-load efficiency of PFM control. The SP7648
features synchronous rectification, a 0.3charging Switch an anti-ringing inductor Switch under-
voltage lockout and programmable inductor peak current. The device CAN be shut down by a
1nA active LOW shutdown pin. A very low 0.288V reference voltage is optimized for driving a
constant current load. By Exar Corporation
