Point of Use Power

DESCRIPTION

The SP6656 is a 400mA synchronous buck regulator that is ideal for portable applications that

use a Li-Ion or 3 cell alkaline/NiCD/NiMH input. The SP6656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 SP6656

seamlessly transitions into 100% duty ratio operation further extending useful battery life. The

SP6656 is protected against overload and short circuit conditions with a precise inductor peak

current limit. Other features include externally programmable output voltage down to 1.0V, logic

controlled output voltage selection, logic level shutdown control, and 140擄C over temperature

shutdown.
