Abstract

This application note delves into the unique symmetrical butterfly-style footprint of the TPS54KB2x, a highly efficient synchronous buck converter. Experimental data uncovers design intricacies and trade-offs, offering insights into the use for industrial and enterprise applications. The report explores how this footprint minimizes parasitics and the impact of removing input capacitors on one side of the IC package.
