Small Sun ZY-T13 busted driver, need your inputs

hi guys, as stated my Small Sun ZY-T13 driver got busted after inserting the wrong end of the batteries. i really love this light of mine and i’m looking for opinions on how to replace it. no chance on repairs cause i can’t solder those very small parts. i tried looking for an original driver over the internet but i can’t seem to find one.

another option is to look for another compatible driver that may work even without the sideswitch. i’d much prefer a single mode on high. i’d prefer a driver which can drive that xml t6 to the highest setting.

thanks
