Part Number: TPS54140A Other Parts Discussed in Thread: LMR33620 ,
Hi,
My customer requests the thermal resistance on the four-layers board condition.
Does anyone have it?

Part Number: TPS54140A Tool/software: WEBENCH® Design Tools Hi team,
I am using webench to design power from below specs,
Vin=10.8-28V, Vo=5V/1A, the feedback resistor is 56.2k//10k. For internal voltage reference is 0.8V, I think the resistor should…
Part Number: TPS54140A Other Parts Discussed in Thread: TPS54140EVM-429 , , TPS54140 Hi
Is it enough to evaluate TPS54140A using TPS54140EVM-429?
Because there is no EVM for TPS54140A.
BestRegards
> 1) TPS54140 and TPS54140A should have samilar output ripple perfromance . There is just Enable threshold improvement in the A version . I think thers's a trivial difference of behavior in very small load. > you can use lower inductance value and…
Part Number: TPS54140A Hello Can someone tell me which current I can use for formula 8 and 9. Is the inductor current IL the same as the wanted current out? If I would use formula 12 To calculate the current I need the frequency result from formula 8 and…
Part Number: TPS54140A To reduce a ripple of TPS54140A in very small load (～less than 50mA) situation, I will choice a low inductance value(4.7uH). Is that OK ? The inductance value calculated by the equation of Lo(min)(in 8.2.2.2 Output Inductor Selection…
Part Number: TPS54140A Hi Robert, Thank you for your advice. Here's the lost images about preceding Q&A. This time, I use ".png" files. Because "paste a word data" couldn't be sent normally . Regards, user4778976 [Circuit] …
Please refer the thread below regarding this matter.
"TPS54140A: Ripple in very small load operation"
I added the waveforms in the above new thread, so please give me a feedback in the new thread.
Part Number: TPS54140A Tool/software: WEBENCH® Design Tools Hi Champs,
when exporting in Webench the simulation of a design to TINA it does only export the startup simulation.
Is it also possible to export the steady state, load transient....simulations…
Part Number: TPS54140A Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models I created a design with TPS54140A in webench and exported in tina-ti. I pulled-up the PWRGD pin to the output voltage (3.3V) but the simulation result…
