Hi Team,

I am Using TPSM84209 in our design and want to have your review on the schematic.

Please let us know what shoould be the trace width for FB Trace.(It should route with 50 OHm)?

Many Thanks

Hi Rajat

The FB trace do not flow large current and there is no specific requirement for the width. Please keep the FB resistors (R2939 and R2937) close to the FB pin and IC GND.

By 50Ohm, do you mean the Z1882? Sometimes we place 50-Ohm(49.9-Ohm is also ok) between the RFBT and Vo in case there is needs to test the circuit loop performance.

Thanks and best regards.

Hi Gui,

Can you review the schematic.

No I was asking for FB trace width we can route it as 50OHM.

Many Thanks
