TPS53114EVM-541
The TPS53114EVM-541 evaluation module can demonstrate a wide-input-voltage (5 V–22 V) to 1.20-V, 4-
A application in a stand-alone module. This module allows a customer to evaluate the performance of the
TPS53114 controller in a typical synchronous, buck (step-down) application. Specifications, test procedure
and setup, design files, and typical performance are included for reference.
