Hi Thirupathi,
thank you for using the E2E forum.
Best is to use the quickstart calculator for that:

Hi Luong,
Thanks for using the e2e forum. LM5122 should be fully capable of supporting this 170W application and the best recommendation I can give at the moment.
Please use our quickstart calculation tool or check for some reference design within our…
Hi Zhang,
Thanks for using the e2e forum. Could you provide me the datasheet of the inductor?
Could you also fill in our quickstart calculator tool for this LM3488 design? https://www.ti.com/tool/download/LM3478-88-BOOST-CALC
Based on this information, we…
Hi Ralph,
Thanks for using the e2e forum. Based on your parameters, the LM5122 device should indeed be capable of supporting this application. For alternative calculations tools to webench, I can recommend our quickstart designer. https://www.ti.com/tool…
Hello,
Go ahead and complete the quickstart calculator file so we can review component selection, power losses and stability.

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 Rayees,
It would likely be 4 phases for 120A (30A/phase) using 40V Q-grade FETs suitable for an automotive 12V battery input.
Is it 120A on each output, both 3.3V and 6V?
Take a look at the LM25143-Q1 and use its quickstart calculator to assist…
Hi Hyunkyu,
The current capability depends on the power stage components, not the controller per se. For 3.3V/64A, I recommend at least two phases. 32A/phase is possible with 40V FETs, although not at high ambient temperature. Have you got forced cooling…
