Hi Mudit,
I am sorry for this misunderstanding. LM5122 is indeed capable of multi-phase operation. I was referring to the implementation of the external cc controller, which I did not find any reference design for with this device.
We do have several ref…
Other Parts Discussed in Thread: PMP9309 PMP7950 and PMP9309 circuit has parallel low side FETs. Is this because you are taking into account the heat generation?
How did you decide inductor value? I think this circuit's ripple current is large.

Hi Adrian,
The 5122 is a synchronous controller and can implement dual-phase interleaved boost. It also utilizes peak current mode control. Please see section 8.1.3 of LM5122 datasheet for interleaved operation.

Hi Alex,
A close reference design to cover your input voltage and total load is http://www.ti.com/tool/pmp9309 . Please submit a request to SEM/PDS group to request a reference design just fit for your particular application.
Thanks,
Youhao Xi
