MP2905 design inquiry

Is it possible to design an input 12V, output 5V/20A circuit with MP2905?

Or is there any other solution?

Hello,

Yes, you can use MP2905 for your specification. Also, we have a module with integrated inductor for your specification i.e MPM3690.

Where do I need to modify to change the circuit to output 5V/20A?

May i have a question,Sir? Is it possible to design an input 24V ,output 12V/8A or 19V/8A with MP2905 ？
i will appreciate it if you have other nice solution.

Hello,

Please see this paragraph in the datasheet.

For your application of 5V/20A you need to change R5 according to the formula given above.
