TPS61230EVM-089: 5V @ 2.1A, 2.3 ~ 5.5V in, Boost

Summary

This user’s guide describes the characteristics, operation, and use of TI's TPS61230 evaluation module (EVM). This EVM is designed to help the user easily evaluate and test the operation and functionality of the TPS61230. The EVM converts a 2.3-V to 5.5-V input voltage to a regulated 5-V output voltage. The TPS61230 is capable of delivering 2.1-A current while the input voltage is above 3.3 V.

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 (BOM), and test results for the EVM.

The TPS61230 is a 5-A switch current limit, synchronous, step-up converter in a 3 × 3-mm, 10-pin QFN package. The output voltage is adjustable.

The TPS61230EVM-089 is set to a 5-V output. The EVM operates with full-rated performance with an input voltage between 3.3 V and 5.5 V. If Vin is below 3.3 V, the output current capability could be less than 2.1 A.
