Other Parts Discussed in Thread: TPS54561 Hi team, I am interested by using the TPS54561 4.5-V to 60-V Input, 5-A, Step-Down DC-DC Converter. However I need to clarify with you the maximum ambient temperature allowed. The datasheet says that the component…
Other Parts Discussed in Thread: TPS54561-Q1 Looking at the datasheet for the TPS54561-Q1, I am trying to figure out why Rjb (12.3°C/W) is so much greater than Rjc_bot (2.2°C/W).
If the junction to case resistance is 2.2 °C/W and we are belly-soldering…
Other Parts Discussed in Thread: TPS54561 Hy,
I use two TPS54561 parallel and it works very well.
No I have a question regarding reverse current through the TPS.
Both TPS54561 has different Input voltages, so it is possible that one Input voltage…
Other Parts Discussed in Thread: TPS54561 Hi I want to use TPS54561, I bought eval board and it was fine. Than I maked a test board but i get to much temperature, it was two layer pcb and than made another, than get gerber over wabenc and test with it…
Other Parts Discussed in Thread: TPS54561 Hello,
I have a Problem with the DcDc-converter, when I do a load jump from 0A-2A@Vout=24V [Vin = 44V]
I use the compensation Network which is calculated by webench, but the result you find attached.
I…
Hello,
I'm trying to calculate the compensation Network with the formulas from the datasheet.
Parallel I do a simulation/ calculation with the webbench tool and the result is, that I have great differences for the component values.
Which result…
Part Number: TPS54561-Q1 Hi team,
Could you please provide the thermal model of TPS54561-Q1? One of my customers need it the do thermal simulation in Flotherm.
The corresponding package is PWSON(10).
Thanks.
Best regards,
Dongbao
Other Parts Discussed in Thread: TPS54561 , TPS54560 Hy,
I have to build a redundant supply, that means I have to independent power supplies, each with a TPS54561.
Now I have to connect the outputs of the tps54561 to guarantee a stable power supply…
Hi,
I have a project use TPS54661, Vin=6~50V, Vout=5.3V, Iout=3A, and had a heavy load issue, when I used under 15Vin and Iout 3A caused Vout unstable.The waveform as below.
What do I need to modify the circuit , please advise?
We do not have the efficiency data for that articular condition. I recommend you use webench to estimate it.
The pspice models can be down loaded here:
You cannot use them for efficiency estimation though. You will need to use webench for that…
