TPS54560: Current sharing with TPS54560

Part Number:TPS54560

Hi there,

I wanted to check if there is a possible way to parallel 2 TPS5450 to double the total current available to the load?

I've had a read of two similar post that says these devices aren't really designed for this purpose and recommends the UCC39002http://www.ti.com/product/UCC39002, to regulate the feedback for each device.

However I also stumbled upon this which seems to show the parallel operation of two very similar devices (TPS54620) http://www.ti.com/lit/an/slva389/slva389.pdf , and just wanted to check whats the main difference between these two devices?

Kind Regards

Ricky
