Tool/software: WEBENCH® Design Tools
Hello Team,
Could you please give some insight into why there might be noise in this system. The issue was fixed by adding a 22uF cap at the connector output or at the load…
Part Number: TPS54561-Q1 Other Parts Discussed in Thread: TPS54561 , TPS54561EVM-555 Hi,
We are planning to use the TPS54561-Q1 for our application to derive 5V from 8V to 13V input. The output current requirement is 4A & we are planning to re-use the…
Part Number: TPS54561-Q1 Hi
If I have no voltage connected to VDD and EN is pulled to VDD (which is not connected to anything), will the device handle 5V connected to the output? Will the device draw any current from the connected 5V into the SW pin…

Hi,
We recently designed a board with the TPS54561 DCDC regulator. The average output voltage is hitting the target of 5V, however we see a switching noise on top of it, with peak-to-peak…
Part Number: TPS54561-Q1 Other Parts Discussed in Thread: TPS54561 TPS54561-Q1, input 22.4V, output 5.1V. Load is minimal <10mA. Design load is 4A. High side switch has very significant ringing, which is causing ~3Vpp noise on the input rail, and ~800mV…
Part Number: TPS54561-Q1 Other Parts Discussed in Thread: LM73606 , LM73605 I am concern about light load condition in my design and want to avoid pulse skipping mode of operation due to light load. From the datasheet i am only getting the statement as…
Part Number: TPS54561-Q1 What will be efficiency of converter when operated at 1Mhz switching frequency ? Input voltage =28V, Output voltage =7.5V, Output current =1.25A.
Im getting efficiency of 80%. Is that the expected efficiency ? Can you provide…
Part Number: TPS54561-Q1 Hello
I have a question about TPS54561-Q1 output capability.
In our design, we need current having 5.3A output capability.
And we try to use TPS54561-Q1.
However this regulator could support 5A output capability which could be…
Part Number: TPS54561-Q1 Dear Sir/Madam:
I need some clarification on TPS54561-Q1. I am using it for converting 50V to 5V. As specified in the datasheet, the Sw node voltage should not exceed -0.6V.
Since my catch diode forward voltage is 0.582V@8A, and…
Part Number: TPS54561-Q1 Other Parts Discussed in Thread: TPS54561 I am using TPS54561 for converting 50V to 5V.As specified in the datasheet,the Sw node voltage should not exceed -0.6V.But my switch node voltage is reaching nearly 900mV..Will it damage…
