Part Number: TPS543C20A Hello,
In our design, we use one TPS543C20A and two TP S543B20 to generate three power rails from 12V.
In order to avoid too much current demand on the 12V, we apply on each converter a external signal on the sync pin (each signal…
Part Number: TPS543C20A Hi Team,
The customer planning to re-layout the next version, how to realize the synchronization function of pin 35? Is pin 35 of the two groups directly connected together
Hopes to synchronize the functions:
1. 5v is master, 3…

Hello,
I am configuring two TPS543C20As in parallel.
How do you recommend I set the feedback for the slave? I did not see an example of this set up in the TPS543C20A data sheet. Maybe I missed that, too.
I am thinking I need to…
Hi Rock,
Do you have vias connecting the GND of the top layer to the layer where PGND connects? It is difficult to see if any exist. I need a bit more clarification before I can help you resolve this. You are able to power up the devices normally. What…
Part Number: TPS543C20A Other Parts Discussed in Thread: TPS543C20 Hello,
I am using two TPS543C20A converters in a two-phase configuration. I am using the TPS543C20_Calculator. The calculator is not set up for multi-phase converter analysis. As a workaround…
Part Number: TPS543C20A Other Parts Discussed in Thread: TPS548D21 I tried to perform Load transient of any combination. Unable to get the proper waveform. Output voltage goes negative. Looks like webench model is not working. Other IC like TPS548D21…
Part Number: TPS543C20A Hi Team,
At present, the output voltage is normal, but 5V can only increase to 7A. 3.3V can only be added to 10A. Cancel a positive and negative remote sense, RSP/RSN feedback directly adopts the PCB board. The waveform is now hanging…
Hi Britton,
How are you doing....
We are currently designing the board layout for our design based on TPS543C20A. We have a couple of questions-
In page 44 of the DS, it is specified to keep 70um of additional solder mask opening around the pad. What…
