Tool/software:
Hi all,
In the EMS test, there was a circuit malfunction of the VCC power supply system around 80 MHz, so we are trying to figure out the cause and countermeasures.
We are checking whether the power supply system is malfunctioning in the EMS test.
Q1: How does the TI DCDC TPS63900DSKR withstand noise immunity?
Q2: Is there any external countermeasure?
I found the following application note.
Layer Design for Reducing Radiated EMI of DC to DC Buck-Boost Converters (Rev. A)
Can the contents of this application note be used for the TPS63900 as well?
If there is any other countermeasure for noise, please let me know.
Best Regards,
Ryusuke
