1 TPS62125EVM-044 Evaluation Module

This user’s guide describes the characteristics, operation, and use of the Texas Instruments TPS62125EVM-044 evaluation module (EVM). The EVM converts a 4-V to 17-V input voltage to a regulated 3.3-V output voltage that delivers 300 mA. The TPS62125 is a high efficiency and small solution for general purpose low power applications, such as those powered from multi-cell lithium, alkaline, or nickel batteries as well as energy harvesting.

Note:

In July 2019, this EVM was updated in order to replace the TDK inductor which had been obsoleted. To accommodate a different inductor footprint, the printed circuit board (PCB) was updated to revision B. This entire user's guide was updated to reference the revision B PCB. The revision A schematic, bill of materials, and PCB layout are located at the end of this user's guide.
