Hi，i‘m sorry to reply to you now,all of problems is that the pcb layout isn't good, in the new pcb,it is work well,and the snubber C is 1nF,that is the datasheet schematic,and the ic can use to the intel's fpga,i have Verified,finally,thank…
Part Number: TPS546C20A Our module contains a TPS 546C20A circuit to convert 12v to 2.2v.
Since the inductor applied to the circuit has a current saturation of over 50A, it was expected that the PMIC would be capable of up to 30A.
However, in this circuit…
Hi Tahar,
Thank you for the continued support. We are moving forward by designing at higher switching frequency of 600kHz. Nonetheless, it would be great if TI could provide additional insights to the root cause of this oscillation, so that in the future…
Part Number: TPS546C20A Hello Team
On data sheet 7.3.8, I have some of questions about it.
Could I know the details in datasheet? Thank you!

Part Number: TPS546C20A We have a design which has SM/PMBus pulled-up later than the power sequence of TPS546C20A through CNTL pin.
This results in “oth” flagged in STATUS_CML (7Eh) register, subsequently pulling-down SMB_ALRT.
By sending…
Part Number: TPS546C20A Other Parts Discussed in Thread: TPS546C23 Hello,
My customer designed the TPS546C20A as below.
TPS546C20A is used instead of TPS546C23 for U2 in the schematic.

Part Number: TPS546C20A
Hi Team,
As we discussed in below post, we can use external FB resistor divider to set the TPS546C20A boot-up output voltage. We want to know do we have any limitations for the R1 and Rbias resistor setting in below schematic…
Part Number: TPS546C20A Other Parts Discussed in Thread: TPS546C20 , Hi Team,
May I know what's the difference between TPS546C20 and TPS546C20A? Can we replace to use them each other?
Thanks.
Part Number: TPS546C20A I have a design in which I have two separate supplies using the TPS546C20A to produce +1.2V and +0.8V. I haven't turned on the +0.8V supply until I understand the behavior of the +1.2V supply. I captured a waveform on my oscilloscope…
