LM5122: LM5122 multi-phase design

Part Number: LM5122
Other Parts Discussed in Thread: LM5170

Hi expert

I want to use LM5122 to supply 1000W application. The boost input voltage is 8V~24V,  and output may be up to 45V,1000W. May I use 4 chips LM5122 and configure with four-phase to design? How much phase would be better to suggested to this application. And is there any limit for LM5122 multi-phase application? It looks like I can use more LM5122 for higher output power designs.
