TPS62085EVM-169: 1.2V @ 3A, 2.5 ~ 6V in


The TPS62085EVM-169 (PWR169-001) uses the TPS62085 adjustable version and is set to a 1.2-V output. The EVM operates with full-rated performance with an input voltage between 2.5 V and 6 V.

The TPS62085 is a 3-A, synchronous, step-down converter in a 2×2-mm, 7-pin QFN package. Both fixed and adjustable output voltage units are available.

The user’s guide describes the characteristics, operation, and use of TI's TPS62085 evaluation module (EVM). This EVM is designed to easily evaluate and test the operation and functionality of the TPS62085.

The EVM converts a 2.5-V to 6-V input voltage to a regulated 1.2-V output voltage that delivers 3 A. This user’s guide includes setup instructions for the hardware, a printed-circuit board (PCB) layout for the EVM, a schematic diagram, a bill of materials, and test results for the EVM.
