Anyone recognize this buck driver?

I pulled this buck driver out of a cheap, low-quality 1-2s JM05-style light.

I plan to replace it with…something else, once I find a good combo of emitter and driver for the light.
In the meantime, I wonder what, if anything, I can do to make this driver more interesting.

Does anyone recognize it? If so, do you know of a source for more info on it, or a common name for it, to make searching easier and more fruitful. Or, barring that, info on the components, or similar drivers?

I’ve come at it from a number of angles myself, but so far, I haven’t turned up anything.

Thanks!

What is the diameter?

Doh! 22mm

I’ll have to check my box ‘o drivers, but that seems to look like one I pulled from an old Trustfire a few years back and replaced it with a buck driver from MTN. I’ll check my box and see if it matches up.

 The driver is not as bad ! The fet ( 9926 )  , can stand up to 6.5 A in continuous duty (!) , only the fly back diode and the inductor  are on the small side .., changing the SS24 with a SK 54 and the inductor  with a bigger one , could give you  at least 4.5 A to the led ( of course , reducing the sense resistor R100 , with some resistances  , placed in parallel ...) . You will be surprised how robust it is ...

Thanks for the info, Cera! The inductor and shotkey did look like weak links to me. I may try swapping parts and paralleling sense resistors at some point.
