Regarding UC3854 and UCD3138 used in the PMP20873 development board, we noticed that they both have three inputs: input voltage, input current, and output voltage. So what are the advantages and benefits of using UCD3138 over UC3854?

One is analog controller and one is digital controller.

It's best not to give hasty and perfunctory answers in the future, as those seeking advice need more detailed explanations

Please share the project details with us. Is there an FAE working with you?

Perhaps it would be best that you read the provided documentation properly as you are asking the most basic questions and wasting the TI Staff's time, when they could be better utilized helping those with more serious queries.

For you, it's a simple question, but for others, if there's no other way, it may take a long time to think. As a TI technical support, if you understand the problem, you can easily and simply answer it. Why pretend to be busy and impatient?
