TPS62150EVM-505: 3.3V @ 1A, 3.7 ~ 17V in, Buck

Summary

This user’s guide describes the characteristics, operation, and use of the Texas Instruments TPS62130, TPS62140, and TPS62150 evaluation modules (EVM). These EVMs are designed to help the user easily evaluate and test the operation and functionality of the TPS62130, TPS62140, and TPS62150. This user’s guide includes setup instructions for the hardware, printed-circuit board layouts for the EVMs, a schematic diagram, a bill of materials, and test results for the EVMs. After the release of the A-version devices in the summer of 2013, these EVMs are assembled with the TPS62130A, TPS62140A, or TPS62150A.

The TPS62150 is a 1-A, synchronous, step-down converter in a 3x3-mm, 16-pin QFN package. Both fixed and adjustable output voltage units are available.

The TPS62150EVM-505 (HPA505-003) uses the TPS62150A adjustable version and is set to a 3.3-V output. The EVM operates with full-rated performance with an input voltage between 3.7 V and 17 V.
