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 in…
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 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 should…
Part Number: TPS54291 Hi, I have problems with non-monotonic power supply on the left side of the circuit (1.8V @ 1.5A) while the other side (3.3V @ 2.5A) is okay. You can view the schematic on the first picture. Non-monotonic power supply can be seen on…
Part Number: TPS54291 Tool/software: WEBENCH® Design Tools Hi All,
I wanted to changed the output voltage from the already designed TPS54291 dual dc-dc regulator IC. I calculated the resistors for the feedback.
But I didn't get the webench design for…
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 5 Volts…
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 inductor…
Other Parts Discussed in Thread: TPS54291 I have a board with 2 TPS54291 step down circuits to generate 4 different levels of supply lines, all in the range of 3.3V down to 1.2V. As input voltage, both circuits operate with 15V. Both circuits (and all 4…
