Intersil ISL6566 Three-Phase Buck PWM Controller with Integrated MOSFET Drivers

This is a Three-Phase Buck PWM Controller with Integrated MOSFET Drivers made by Intersil Americas Inc.

 

The bottom left and bottom right sections appear to be mirror images of each other, pairing this information with the block diagram provided by the datasheet (pdf1.alldatasheet.com/datasheet-pdf/view/180639/INTERSIL/...) I think the right half of the block diagram is the bottom half of this image.

 

There are three repeating structures on the right half of the block diagram, If you look at the bottom middle half of this die shot you can see that if you rotate it 90 degrees clockwise it looks almost identical to the bottom left section.

 

This leads me to believe that these sections are each responsible for one of the three phases.

 

There is writing in the bottom right corner, top left corner and top right section.
