I am have been using the TPS546D24A and now I see the TPS546D24S on-line, this brings up several questions?
Is…
Hi Tomoya,
As you suggested, we removed the supply to EN/UVLO pin and connected it to ground so as the converter function to be stopped. We are using 5V power supply so it will enough for AVIN and above UVLO for the PMBus to be active. But still there…
Hi Gareth,
That seems good to me. In the case of 13.2Vin to 3.3Vout at 9A, if the ambient temperature is too high, I wanted to make ensure the device could support your application. That being said, if you plan to operate the device at room temperature…
Part Number: TPS546A24A Hi expert,
Two simple questions below:
1. I notice that all this 'SWIFT' series buck converters, have differtial sense of Vo, e.g. TPS546A24, what is the reason for it? Why not use single-end voltage sense like typical buck…
Hi Kurt,
I wanted to clarify that whether a specific PMBus command is initialized to the value selected by the detected resistance or stored NVM memory depends on the command bit in the PIN_DETECT_OVERRIDE PMBus command. The factory default setting…
Hi Srinivas,
Using only ceramic output capacitors with the TPS546B24A is generally acceptable as long as you meet the required minimum capacitance and output impedance for stability. You can find information about the necessary output impedance and…
Hi Eugene,
I’m happy to help you review the layout. Please share it when you’re ready. We also have an Excel tool with a checklist for the layout review that you can use. We find it helpful.

Hi Jeff,
Your current source setup on the third slide is correct, but the converter seems unstable. Make sure the control loop is compensated properly with the right L and C. Use the attached Excel design calculator to help you with the design and compensation…
Hi JH,
I have attached the Excel calculator, which includes the design calculator and a schematic/layout review checklist. I filled it out for you this time, so please use it to review the layout.
