Part Number: TPS54291 Other Parts Discussed in Thread: TPS54292 , TPS65270 Hello,
I have been recently trying to perform simulations on TPS54291 Dual output Buck convertor. I tried simulating in LT Spice and PSpice for TI. Both the time an error appears…
Part Number: TPS54291 Hello Sir/mam,
Good Day.
I want to generate 5V/2.5A output instead of 1.2V/2.5A at Channel 2 output by using VIn = 12V.
I would like to generate 5V/2.5A ouptut at Channel 2 using TPS54291 Buck IC(Instead of 1.2V as mentioned…
Part Number: TPS54291 Tool/software: WEBENCH® Design Tools Hi,
The spreadsheet in the original post was very helpful. I didn't catch the mistake in the equations in the data sheet. When I look at the example design there are components on it that are…
Part Number: TPS54291 Other Parts Discussed in Thread: TPS54292 , Hello,
Currently I use TPS54291 with 600kHz frequency. If I change to use TPS54292 with 1200kHz, output voltage and power keep original, what should I change?
Maybe the comp parameters…

Hi Filipa,
Based on this measurement it does look like this is likely not related to an overload on the output.
When you see this issue on the 1.8V output, do you also see switching stop at SW2? When hiccup is triggered in the TPS54291, both PWM outputs…
Other Parts Discussed in Thread: TPS54291 Hi,
I use a TPS54291 for the electronic supply of my robot. I use 3.3 Volts for internal supply with around 300 mA of consumption and 5 Volts for external supply. I mean with external that I left a pin with…
Other Parts Discussed in Thread: TPS54291 , LM2678 Hi,
How are you?
We are selecting the right discrete components to build a dc dc converter with a tps54291 chip...
We have some questions about the inductor selection:
Why did they choose that…
