UCC28C44-Q1: A Student's Question on a Practical Workflow: Is Modifying Reference Designs a Valid Path?

Part Number: UCC28C44-Q1

Tool/software:

Hi everyone,

I'm a final-year electrical engineering student and I'm at a point where I need some validation on a design approach from experienced professionals.

For my own learning, I am designing a DC-DC flyback converter completely from scratch using UCC28C44-Q1. However, I am also on a university team where meeting tight deadlines is often the most critical factor for our success. To balance these two worlds, I've been considering a more pragmatic approach for our team projects: starting with a texas instrument's reference design (.PcbDoc) and modifying it to fit our specific needs (e.g., changing the board shape, adding a sensor section, etc.), then generating new fabrication files.

My core question is very simple: Is this a valid and reliable professional workflow to accelerate development when deadlines are critical?

Right now, I'm not looking for deep technical details on how to do it—I will do my own research on that part once I know this is a sensible path. What I truly need is to hear from experienced designers whether this approach is a legitimate way to deliver functional products on time, especially in a team environment.

Any confirmation or personal experience you can share on whether this is a "good road to take" would be incredibly helpful for me to see a clear path forward.

Thank you for your time and guidance.

  • Hello Huseyin,

    Yes, that is typically how development works. TI provides our EVMs and Reference Designs for free to serve as an example for customers to start off with and modify to fit their own needs. All of the schematics, layout, test report, etc. are public and free to use.

    Think of a software SDK that has sample code. Any software package must also provide example code so we understand how to use the product, which makes it more likely for us to use it. Our reference designs and EVMs serve the same purpose. Ultimately, we want you to use TI products, so we will provide support to get you started on your development with a TI product.

    Regards,
