Ferrite bead for Aurix MCU

[abhishek-2138]

I am using TLF35584 power management IC for AURIX MCU.

Where should I place the ferrite bead, is it near to VDD pins of MCU or directly at the output of PMIC internal LDO?

Will this help to reduce radiated emission or conducted emission?

Hi @abhishek-2138 

Thank you for your interest in Infineon Semiconductor products and for the opportunity to serve you.
I'd highly recommend you refer to the attachment for design, which is the schematic of the TriBoard TC397.
Actually, it doesn't definitely need the ferrite bead.

BR,
