Other Parts Discussed in Thread: TPS54561 Hi,
My customer is considering the TPS54561 on following condition.
Could you confirm whether there is problem for thermal?
- Vin : 35~60V
- Vout : 5V
- Iout : 2.0A
- Ta : 60℃
- Board size(whole…
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…
Part Number: TPS54561 Tool/software: WEBENCH® Design Tools Hello,
I try to design a DC/DC converter from 28V to 18.5V with switch mode regulator which can supply 2A current. When I use Webench tool to design and see the performance of the circuit…
Part Number: TPS54561TPS54561 is used to create a 13V, 5A regulator, Vin is 48V.
With a load of 5 ohms (2.6A), the output voltage measured about 13 VDC with a ripple of about 3V. The inductor current shows to top waveform below, and the…
Other Parts Discussed in Thread: TPS54561 I am using TPS54561 under the following working conditions:
Vin min = 20V
Vin max = 50V
Vout = 17V
Iout max = 3.5A
Modified the EVM of TPS54561 usign the component selection recommended by Webench Designer…
Fedor,
The power section of the layout can be improved. When SW goes high the current has to go through a thin trace to get to L, then from L through a thin trace to get to C6, then through thermal reliefs to get back to GND, then thermal reliefs to…
Part Number: TPS54561 Other Parts Discussed in Thread: LM76002 , LM76003 Tool/software: WEBENCH® Design Tools HI,
Been beating my face against WebBench all afternoon. Trying to find a solution for 20 to 60 Vin, 18Vout, 2Amp at 1.6Mhz. Every time I…
Hi,
It is mentioned that "The top and bottom layers are 2-oz copper" in the EVM user's guide.

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…
Part Number: TPS54561-Q1 Other Parts Discussed in Thread: TPS54561EVM-555 , TPS54561 Hi
We want to use TPS54561-Q1 in a design where the nominal input voltage is 24 -28.5 and the output is 12V
To verify the design I have modified a TPS54561EVM-555…
