Olight driver R&R

Evening,

I have an Olight I15 that one of the little coil widgets broke off the driver board the last time it was drop checked. Any suggestions on a good driver to replace the old driver with? According to the "manual" that came with the light it has a CREE XR-E R2 and could use either 1 AA or 1 RCR14500 battery. I used an AA battery because they provide them at work. I do not need the strobe or SOS modes and very seldom dialed the output down from max so either a single mode or low-medium-high is good. The old driver is circular, but with two ears to lock the driver in place against the twisting action when using the lens to select modes. Thus it measures 18.75mm at its maximum width and 18.11 at its narrow section. Any other info needed to help in deciding what replacement will bring my light back to life.
