SP6654 Description
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%...
