TPS630250EVM-553: 3.3V @ 2A, 2.5 ~ 5.5V in

Summary

This user’s guide describes the characteristics, operation, and use of the TPS63025xEVM-553 evaluation module (EVM). This EVM is designed to help the user easily evaluate and test the operation and functionality of the TPS630250, TPS630251, and TPS630252. The EVM converts a 2.5-V to 5.5-V input voltage to a regulated 3.3-V output voltage that delivers up to 2 A. This document includes setup instructions for the hardware, a schematic diagram, a bill of materials, and printed-circuit board layout drawings for the evaluation module. Throughout this document, the abbreviations EVM, TPS63025xEVM- 553, and the term evaluation module are synonymous with the TPS630250, TPS630251, and TPS630252, unless otherwise noted.

TI's TPS63025x are highly efficient, single-inductor, buck-boost converters in a 1.77 mm × 2.09 mm, 20- pin WCSP package. TPS630250 is an adjustable output voltage converter. TPS630251 as well as TPS630252 are fixed output voltage converters with 2.9 V (TPS630251) and 3.3 V (TPS630252).

The TPS63025xEVM-553 uses the TPS630250 adjustable version that is programmed with an external feedback divider to an output voltage of 3.3 V. Alternatively, TPS630251 or TPS630252 fixed output voltage versions can be assembled. Therefore, the resistors R1 and R2 have to be disassembled and a 0-
Ω resistor placed at R1.
