Hi Alain,
Thanks thanks thanks - I am a lot closer thanks to your post. I know believe it does complex PWM for multiplexed LED illumination.

That chip is likely made specificly for that manufacturer. Here is a link to similar off the shelf chips by supertex.

Joe,
Thanks for the link - I stumbled across that after Alain posted the main supetex site. That is what led me to believe this 24 pin beast is PWMing stuff since most of the smaller packaged devices that are on the website are PWM units. I also confirmed this yesterday with my scope. I also have a (maybe not so good) lead that pelikon may be involved ...? time will tell and thanks again.
Thanks,

Good, nice you found at least some info. Like Joe S, i think it's a custom made model. Specific information on THIS specific one seems impossible to find.
Good luck Mr RabbitResearch... euh... sorry... Paul

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.
