General 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’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 SP6651A seamlessly transitions into 100% duty ratio operation further extending useful battery life.
