Testimonial: "No. That is incorrect one. It is cd33 datasheet."
Yes, I post links to show something is NOT available. That would be the company to ask though as that is their specialty. Finding stuff is what I do best. If I can't find it, then it doesn't exist online. I spent about 25 minutes looking for you. Your power IC may be custom made and patented / copywrited to the designer / maker of the PC architecture.
