MP4201 Parallel or increased power

DC-DC Power Converters
1

Hello,

My company is looking to develop a 4 switch buck boost converter that is bidirectional. The MP4201 looks like it could be a great candidate. The only issue we have with it is, we need to be able to get to 50 Amps or input or output current.

Is it possible to either parallel two of these converters, or possibly update the sense resistor to 0.5mohm to increase the current limit to 50 amps?

The components would obviously also need to be sized such as the fets and inductor to handle it. But I was not sure if there was anything that stopped us from doing that to increase the power level.

Thanks!

Hi Isabella,

I checked my email and did not see anything come through. Is there an email I should reach out to?

Thanks!
