TPS62175EVM-098: 3.3V @ 500mA, 4.75 ~ 28V in

Summary

The TPS62175 is a 500 mA, synchronous, step-down converter in a 2x3 mm, 10-pin WSON package. Both fixed and adjustable output voltage units are available.

The TPS62175EVM-098 (PWR098-001) uses the TPS62175 adjustable version and is set to a 3.3 V output. The EVM operates with full-rated performance with an input voltage between 4.75 V and 28 V.

The user’s guide describes the characteristics, operation, and use of the Texas Instruments TPS62175 evaluation module (EVM). This EVM is designed to help the user easily evaluate and test the operation and functionality of the TPS62175. The EVM converts a 4.75 V to 28 V input voltage to a regulated 3.3 V output voltage that delivers 500 mA.

The user’s guide includes setup instructions for the hardware, a printed-circuit board layout for the EVM, a schematic diagram, a bill of materials, and test results for the EVM.
