Identify parts help , drivers , thanks old skool i believe

Hello, well i was digging around in the parts bin before i got sick i was gonna build a super duper maglite and i have these things laying around , i know that the leds are p7 and mce but what are these drivers ? and what can they do like with a xml :) thanks for your time

btw i pretty sure i got them from kaidoman back then , thanks for any help

The driver could be this one or this one

Looks more like the first one to me , can it be used for XML ? Or a triple XML ?
