TPS53647: The EMC/EMI report of TPS53647

Can someone help me? Your reply will be highly appreciated.


Regards

Hi Jenny,

TPS53647 is a driveless controller.
The EMC/EMI should be from inductor and FET, not from controller.
I don't think we have EMC/EMI report for controller.

Thanks

Hi Qian,

Thank you for your reply.

Hi expert,

one more question need you help, we are doing some system thermal simulation and found TPS53647 mosfet (csd95372b) juction termperature is high to 135°C, 

to my conduse is that csd95372b datasheet page 4 show that max operation junction Tj is -55 to 155°C and the recommended operation temperature is -40 to 125°C,

if i have good understanding this sentence, the mosfet's maximum Ambinet temperature is 125°C, and the maximum Tj is 155°C, right?

best regards,

bruce

Hi Bruce,

What's the current rating and ambient temperature during the test?

Can you send the layout screenshot to Q-CHEN@TI.COM?

Just want to check if layout is fine.

Thanks

Hi Qian,

One more question is how about tps53647 output voltage adjust accuracy? I didn't find any information on the datasheet, thanks

Best Regards,
