Part Number: TPS543C20A Tool/software: Hi
We have used multiple 0 ohms isolation resistors at the output of the buck. This is to help us during testing phase by isolation the load and checking initially. We are using this to power Zynq ultrascale+(XQZU19EG…
Part Number: TPS543C20A Tool/software: Hi Britton,
Couple of last questions before I release the design.
1. The output cap. configuration in the Excell calculator tool suggests a feed forward cap. for the 6 100uF ceramics I've included in the design…
Part Number: TPS543C20A Tool/software: Team,
Kindly check on the EN Pin logic VIL and VIH spec in the datasheet, I couldn't find it in the published datasheet. Thanks！

Part Number: TPS543C20A Tool/software: Hi Britton,
I think I've asked this before; I apologize if you've already answered this.
I want to use the BP regulator for an external circuit.
To implement this circuit, I'd have to alter the 100K resistor…
Part Number: TPS543C20A Tool/software: Hi Britton,
Final question before I release this design.
For the RS_P &RS_N lines, I provided pictures of the schematic/layout.
Does how I routed the input to the sense amplifier look correct? The data sheet…
Part Number: TPS543C20A Tool/software: Hi Britton,
Is it okay to leave the MODE/RAMP pins open as No Connects?
I believe we talked about this, but I just wanted to double check.
Thanks,
Matt
Part Number: TPS543C20A Tool/software: Hello,
I am using TI PSPICE to simulate the transients in my design.
I have been able to successfully run the simulations as is from the TI TPS543C20A downloads page.
I also was able to alter the startup trans simulation…
Part Number: TPS543C20A Tool/software: Hello,
I'm making sure the way I am setting up PGOOD doesn't stress the drain on the FET controlling the output logic on PGOOD.
If PGOOD is low the FET should pull PGOOD node to ground sinking 9.5mA through…
Part Number: TPS543C20A Tool/software: Hi Britton,
I attached the schematic and the filled-out design calculator for your review as we discussed.
I did my best to fill out the schematic checklist on the second page of the design calculator.
I have a few…
Part Number: TPS543C20A Tool/software: Hi Britton,
Another question on this part. We noticed on our current switcher that the ringing from the switching wasn't negligible. Do you have any recommendations on how to reduce this . The data sheet mentions…
