Hi Jeff,
Jeff YANG said: Additionally, could you recommend the values of inductance and capacitance for a 700A/µs case?
I recommend using our Excel design tool, which I will attach below. In this tool, you can enter the load step and the undershoot…
Hi Rannie 1. you can use the Power fusion Gui in off-line mode to select the pin strap in pin strap tab
2. you can also use the excel calculator for designing which i am attaching here and also use the pin strap tab to select thr pin strap table

Hi MM
Looking at the excel calculator attached and assuming the derating of cap selected is correct
the Fcoi calculated is 216.67kHz which is max current loop bandwidth
But with selected compensation code 25 the BW-ILOOP is 270kHz which make the…
Part Number: TPS546D24A Tool/software: I've been working with webench and the calculators provided on the device product page and find a discrepancy in the results.
The goal is to have a stable, 2-phase 13V to 5V converter at 35Amps
I first run…
Hi Joseph,
Thanks for the updates. I have attached the final schematics and excel power calculator for review confirmation.
Schematics.

Part Number: TPS546D24A Other Parts Discussed in Thread: TPS546D24 Hi,
Can you please review my compensation spreadsheet? I'm hoping the loop bandwidth can be improved, and perhaps also phase and gain margin. If I need to adjust the inductor value as…

Hi team,
they try 3.3V with 0.68uH , 650kHz and code 28 today , transient all failed,
would you advised which should they change to improve?
for example , the tolerance is +-5%, the maximum 3.465V barely have…
Hi Peter,
No, I think you got it wrong ,
these 650KHz tests were all 0.9V power rail which you already recommended to use compensation code 30 last week.
so they're all tested in code 30 and 0.22nH.
The 3.3V today is the another new power…
Part Number: TPS546D24A Other Parts Discussed in Thread: TPS549D22 Hi Peter,
I am measuring excessive ripple on all my 3 rails. (0.9V quad, 1.0V quad, and 1.2V single), mainly because the consumption is currently too low.
Typical rail configuration…
