The SP6654 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 SP6654’s proprietary control loop, 20μA light
load quiescent current, and 0.3Ω power switches provide excellent efficiency across a wide range
of output currents. As the input battery supply decreases towards the output voltage the SP6654
seamlessly transitions into 100% duty ratio operation further extending useful battery life. The
SP6654 is protected against overload and short circuit conditions with a precise inductor peak
current limit. Other features include programmable under voltage lockout, externally programmed
output voltage down to 1.0V, logic level shutdown control, and an open drain power
good indicator when VOUT is above 94% of its programmed value. SP6654EU SP6654EU/TR SP6654ER SP6654ER/TR资料下载
