This reference design is a triple output 3-A/ 2-A / 2-A point-of-load converter in a tiny 0.5" x 0.875" (12.7 mm x 22.2 mm) solution size. TPS65261-1 fully integrates three 3-A / 2-A / 2-A buck regulators into a small 5mm x 5mm QFN package. It features dedicated enable and soft-start pins, which make the tracking and sequencing easy to implement. The layout is size optimized. It is a triple output building block for size-constrained applications.
