I have identified the chip on the Pololu 5V, 5A buck converter as my2101 330, but I am having difficulty finding information about this chip on any platform. I've checked the Pololu resources page (www.pololu.com/product/2851/resources), but the datasheet is not available there.

Could someone please guide me on where I can find the datasheet for the my2101 330 chip or provide relevant information about its specifications? Any help would be greatly appreciated. enter image description here

So, I guess the device might be a MIC2101. Microchip have this as a buck converter in the same package shape: -

I'm not saying it definitely is the device on the Polulu module but, it's worth further investigation. Packaging ID information looks similar (note the "Y"): -
