The 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  
featuressynchronousrectification,a0.31 chargingswitch,ananti-ringinginductorswitch, 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.
