Product details

The TPS25940LRVCR: Derate the 5.3A output at the high end — the exposed-pad package's thermal resistance to the board sets the real limit, not the silicon alone.

Package and board-fit checklist

20-WFQFN with exposed pad, supplier package 20-WQFN measuring 3x4 mm. Without that, the current limit folds back earlier than the 5.3A spec suggests. Available in Tape & Reel for production reels or Cut Tape for prototype builds. The small footprint means hand-soldering is possible with a hot-air station and a fine tip, but the exposed pad needs a stencil for consistent solder paste coverage.
