Wish to design a DC-DC buck converter

[MD MUBDIUL HASAN]

Hi,

Suggest me a control chip or design for a DC-DC buck converter.
Here is the specification.

A search on Digikey would be an excellent start.

Maybe a TI chip, then use TI's design tool.

Thank you.
I already request to TI. No reply yet. This application seems to be old.

What about this one, https://www.analog.com/en/products/lt3800.html#product-overview

TPS40061, TPS40060, LM5088, LM5088 External MOSFETs.​

TI has 8 parts that will do 5A with internal MOSFETs. very simple. Use two in parallel.
Just form TI.

Just for make sure, this should have following,

.OVR protection
OCR protection
"ENABLE" Signal
"FAULT" signal
1 LED indication.

The newer chips offers a lot of options.
