Marc,
Please take a look at our reference design:
www.ti.com/.../PMP11769
This has both a volume knob on the front end as well as the TPA3251 which supports the power level you are asking about.
TPA3251:

Please refer to the example at http://www.ti.com/tool/PMP7837
This is for the LM5122 but the same circuit structure can be used for the LM25122-Q1.
There is also an 700W peak power reference design with the LM25122-Q1. The link is at: www.ti.com…
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 Delmore,
Thank you for your question. Here is a reference design for a single phase Boost with 200W output power, https://www.ti.com/tool/PMP20093 theoretically this can be extrapolated to a dual phase boost as per your specifications.
The best…
hi Andriy,
I see... well, it should work even if you need to tune it up, plus the resistors have to be 1% or better to avoid mismatches...
I would also consider a monolitic solution, like the TPA3255 ( www.ti.com/.../tpa3255evm ) or, even better,…
Hello R.Rajesh,
Unfortunately for this design, Gerber files are no longer available.
The Schematic BOM and layer plots are illustrated in the User's Guide on the EVM page for this design.
The EVM is still orderable as well: http://www.ti.com/tool…
