TPS56425X evaluation module (EVM) is a simple, easy-to-use, 4 A synchronous step-down converter in SOT563 package. TPS56425XEVM is a fully assembled and tested circuit for evaluating the TPS56425X step-down converter. This EVM operates from 3 V to 17 V input, 12 V nominal, and provides a 1.05 V output at 4 A. The EVM also includes AC signal injection terminals for feedback loop measurements.
This user's guide introduces the TPS564252EVM, TPS564255EVM, and TPS564257EVM. These three devices differ in their light load behavior. The TPS564252 operates in Eco-mode, the TPS564255 operates in OOA mode, and the TPS564257 operates in FCCM mode. This user's guide contains information for the TPS564252, TPS564255, and TPS564257 as well as support documentation for the TPS564252EVM, TPS564255EVM, and TPS564257EVM evaluation modules. This document also includes the performance specifications, board layout, schematic, and the list of materials of the TPS564252EVM, TPS564255EVM, and TPS564257EVM.
