Tried asking this in the open source controler section, never got an answer, but: Anyone used the Texas Instruments UC3770AN chip, what about the A3959SBT from Allegro?    |

| I've got a A3959 design in works. Looks to be a great alternative to the expensive LMD18245's!

| Not really, when Allegro released the A3986, all my attention went to it. SInce the A3986 allows a higher current implementaion at probably less cost, It's more likely a better solution.
