Hello JT,
Thanks for using the e2e forum. The LM5122 should be a good fit for this application as it meets the specs and is multi-phase capable.
Here is a 600W four phase reference design which might answer some of your questions: https://www.ti.com/tool…
Hi Kris,
Thank you for evaluating our device.
For this power level, we usually do not recommend using a 1PH design, because it will make device selection difficult.
We recommend using multi-phase parallel to reduce the power of each phase…
Hi Roy,
There are several other relevant boost reference designs that could be useful here. You may want to check with your customer if this is a continuous power or peak power rating.

Hi Richard,
Thank you for answering my questions, that article you provided was very useful. I have an initial design that I think will work now and give me a good place to start prototyping. I have a few additional questions regarding the PMP11112 reference…
Hi,
Unfortunately I cannot publish full schematic. I attach one stage (they are identical) and block diagram. Generally I based on your PMP11112 design. Below are some parameters:
Uin = 30-50V
Uout = 60V , Pout = 1kW (this is what I want to reach with…
Hi Hugues ,
Is EMI a concern for your application ? Synchronization will be helpful in avoiding beat frequency .Further out of phase clocks would be helpful particularly in reducing MW band harmonics .
You may use 555 based timer circuits as used in…
