DESCRIPTION
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
features synchronous rectification, a 0.3鈩?charging 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.
