The ic should be cheap and easily available.

ALL ICs are cheap and are readily available HERE, but I do not know about in your country. Maybe you should ask on a forum in your country.

Simply go to the website of your electronic parts supplier and search for the part you want.
I go to the website of my favourite semiconductor manufacturer (Texas Instruments) and search for what I want. My electronic parts supplier has all their ICs available.

Just now I searched TI's website for a switching buck regulator with the spec's you want. They have 185 devices available in many different size packages.

Usually popular parts are easily available.
I guess the parts listed below are some of well known DC-DC switching regulators.

1. LM2575 (rated current=1A)

2. LM2576 (rated currrent=3A)
Datasheet link: https://www.ti.com/lit/ds/symlink/lm2576.pdf

They are available in several fixed output voltage (including 5V) and an adjustable output voltage versions.
