EK-TM4C1294XL: Portable power supply for EK-TM4C1294XL

Part Number: EK-TM4C1294XL
Other Parts Discussed in Thread: TPS63001, TPS63002

Hello, 

I have a question. I am planning to use  EK-TM4C1294XL board https://www.ti.com/tool/EK-TM4C1294XL for a project. I was wondering how to make the project portable. To do that I  can't power up the board through USB. I need  a power supply. I was searching and I came across this power supply design https://www.pcbway.com/blog/technology/220Vac_to_5Vdc_Transformerless_Power_Supply_Using_LNK304_5b2e2d7d.html

This design is meant for Arduino. My question is, is there any problem if I use it for  The TM4C1294 Connected LaunchPad Evaluation Kit?
