Dear Team,

I am looking for 5~20Vin to 5Vout/5A buck solution.

And find PMP30224.3 which design with TPS54531.

Did you have suggested solution for this application? If yes, please let me know, thanks.

Regards,

Ben

Hi, Ben

Actually, TPS54531 cannot support the real 100% duty cycle.

And it also cannot achieve 5Vin to 5Vout with 5A loading.

As I know, there is no devices can support your application.
