LM25145: Question single sided assembly

Hello:

I want to integrate the LM25145 into our product but I had some general questions. All of our PCB is a single sided assembly - I wanted to recreate the circuit from the LM5145EVM-HD-20A module as it is exactly what we need for our device. However, I wanted to ask if there are any concerns on doing the layout with all the components on one side of the board, or if it is not advisable. Could you share what we should keep in mind when doing the layout with all the components on a single side? If it is not advisable, could you suggest another alternative? We are looking for a 5V 20A DC/DC buck converter (Vin: 22V to 30V).

Also, are there any recommendations on bulk capacitors on either the input or output of the system?

Thank you!
