Hi Team,
Here is my customer's SCH and would like to know TPS563201's simulation result of gain/phase margin. I found WEBENCH doesn't have this kind of simulation function. Could team help to run simulation? If additional information is needed for running simulation, please let me know.
Thanks very much.

Hi Vincent,
loading is 1.5A, right? will I run simulation at 1.5A. is it ok?

Hi Edwin,
Allow me to check with customer and get back to you.
Thanks very much.

Hi Edwin,
It is confirmed that we can run simulation at 1.5A.
Thanks very much for your support.

Hi Edwin,
R&D is requested by his customer to have the worst case's simulation result. His customer replied him "Capacitor value derated with DC voltage, tolerance and dielectric derating over temperature. L can be derated using DC current temperature and tolerance. Include the worst case tolerance."
Could you please help to simulate it again with the worst case of L and C? There are two units of TPS563201 designed at this system.
1. 12V to 3V3. Run simulation at 2A. As you mentioned if removing one 47uF output cap can get better result, please remove the cap.
Inductor's spec.
Capacitor's spec.
2. 12V to WIFI_3V3. Run simulation at 1.8A.
Inductor's spec.
Thanks very much.

Hi Vicent,
I will send the test result by email. Because there are two many waveforms. i close this request.
my Email edwin-zang@ti.com...
