The SP6648 is an ultra-low quiescent current, high efficiency step-up DC-to-DC converter ideal for single cell, dual cell alkaline and Li-Ion battery applications.

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.

 

FEATURES Ultra-low 12µA quiescent current 400mA output current at 2.6V input: 3.3VOUT 94% efficiency from 2 cell to 3.3VOUT Wide input voltage range: 0.85V to 4.5V Operation down to 0.7V after start-up 3.3V fixed or adjustable output Integrated synchronous rectifier: 0.3Ω 0.3Ω switch Anti-ringing Switch Technology Programmable inductor peak current Logic shutdown control Under voltage lockout at 0.61V Programmable low battery detect Single or dual cell Alkaline Small 10-pin DFN package and industry standard 10-pin MSOP

APPLICATIONS Camera flash LED drivers Wireless mouse PDAs Pagers Medical monitors Handheld portable devices MP3 players
