3 amp Single mode buck driver. Got any ideas?

Flashlight Modding and DIY Parts

I’m using a 3.7V LED with 3x 18650s. I need a buck driver that is current control or constant current (however you say that), but does NOT have to be round. Something like this would be ideal, but with CC. I am afraid if I used the one in the link the output would drop when the over voltage wore off.

The space I have to work with is about 37mm long x 26mm wide x 10mm tall.

Thanks in advance BLF!
