I am powering an Intel Arria 10 FPGA and am using your power demo board design as a starting place: https://www.infineon.com/cms/en/product/promopages/Altera/

Is there a recommendation for a different IR MOSFET than the IR3555-IR3557 to use with the IR35204? These FETs are obsolete or unavailable.

Thanks,
Dan

Hi,

Thanks for posting at Infineon Community.

We recommend you to go with the IR35204 Controller + TDA21472 Power stage.

Please note below points

1. TDA21472 and IR3555-IR3557 Footprints are not identical.

2. Functionally fine-tuning is necessary with TDA21472.
