Hello, you can look at LM25119 for this application. There is a TI reference design for quarter brick size below. This is the closest we have.

I want to transfer the 12V power directly from car battery to 0.85v/50A and 5v/10A. It is used on the car so the chip should be automotive grade and the input port can tolerate the voltage deviation…
Hello Dhimat,
We do not have any dual switchers with integrated fets rated to 40V.
Our dual integrated fet switchers, like TPS55386, are only good to 28V.
For single switcher with integrated fets see:
TPS54540 TPS54040A TPS54140A TPS54240 TPS54340…
Alpha,
We don't really have any device that can do this. A dual synchronous buck might work though I'm not sure how well you will be able to control the timing of the FETs. http://www.ti.com/product/lm25119q
