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…
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…
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…

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 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…
Part Number: TPS543C20A Other Parts Discussed in Thread: UCD90160 Hello,
We need to use the TPS543C20A with a UCD90160 margining IC. We want 1.0 V output with the margin range 0.99V to 1.01V. According to the UCD90160 application note and the UCD90160…

I am an LTSpice user trying to learn PSPICE. It's a big challenge so far. Has anyone downloaded the TPS543C20A PSPICE model from the TPS543C20 product support page? I am having…
Part Number: TPS543C20A Hello,
My customer did a PSpice simulation after modifying the TPS543C20A PSpice Transient Model file in TI.com to the customer's schematic below.
TPS543C20A_TRANS.DSN
The simulation result is as follows.
