Point of Use Power
DESCRIPTION
The SP6651A is a 800mA synchronous buck regulator which is ideal for portable applications that
use a Li-Ion or 3 cell alkaline/NiCD/NiMH input. The SP6651A鈥檚 proprietary control loop, 20碌A(chǔ)
light load quiescent current, and 0.3鈩?power switches provide excellent efficiency across a wide
range of output currents. As the input battery supply decreases towards the output voltage the
SP6651A seamlessly transitions into 100% duty ratio operation further extending useful battery
life. The SP6651A is protected against overload and short circuit conditions with a precise
inductor peak current limit. Other features include programmable under voltage lockout and low
battery detection, externally programmed output voltage down to 1.0V, logic level shutdown
control, and 140擄C over temperature shutdown.
