Overview

The Design Calculator Plus Application Note (SLVA352A) Calculator Tool calculates the critical external component values for the TPS54620/TPS54622/TPS54521/TPS54320/TPS54618/TPS54418/TPS54318/TPS54218/TPS54319. The calculator includes power stage design, feature design and Type II and Type III compensation designs using the datasheet equations and application note (SLVA352A) equations. The calculator utilizes generic power stage and compensation design algebra which can be modified for most of current-mode step-down DC/DC converters
