Part Number: TPS543C20A Tool/software: According to the datasheet :
8.4.6.1 Ramp Selections RAMP pin sets internal ramp amplitude for the control loop. RAMP amplitude is determined by internal RC, selected by the resistor connected from MODE pin to GND…
Part Number: TPS543C20A Tool/software: Hi
We are using TPS543C20ARVFR in our design to provide 0.85V as VCCINIT supply for Zynq Ultrascale+ FPGA.We have used the buck as per the below implementation. We want to implement power on/off using a push button…
Part Number: TPS543C20A Tool/software: Hi. For some reason in my design the stand-alone regulator not starting up if MODE pin remains open. Using 23.7kOhm for MODE is OK. According to the datasheet keeping MODE pin floating is valid option. What I am…
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'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…
