Hello team,

- Vout: 24Vdc

- Iout: 12.5A(max)

- Pout: 300W(max)

Can you recommend the appropriate device?

Also, if LM5122 be used, multi-phase is mandatory?

Hi Austin,

Thanks for using the e2e forum.
LM5122 should be the best suitable device for this application.

300W should still be feasible with a single phase design if this is preferred. Please select suitable power stage components (inductor, FETs) according to the power requirements.

You can also look for reference designs here:

One example for a one-phase 200W application is here, but maybe you even find a better reference.

Please let me know if you have additional questions on the LM5122 device.
Best regards,
Niklas
