Part Number: TPS54331 Tool/software: I am using the TPS54331 IC to convert 5 V input into a 3.3 V output. I am using the schematic as designed in webench. I am simulating on LTSpice.
However, when i give a 5 V input, I am getting an output of 2.9 V. …
Hi Sachin
I simulated using Webench and the Vo rising curve also has a slight twist. This should be normal and is not harmful to the system.
You can disconnect L1, connect Electronic load and do the start up test and see if the waveform is same.
Thanks…
Part Number: TPS54331 Tool/software: Hi team my customer is using TPS54331 and the vin is 12V and vout is 5V.
when the Vo is connected to MCU, the output will be 8V and the Vsense will also be 1.3V. The SCH is as attached and the Vonis 5V when connected…
Part Number: TPS54331 Other Parts Discussed in Thread: LM66100 Hi all, I have a setup with a TPS54331 configured to 5V output and want to OR between a primary(24V) and secondary (5V USB) power sources. The secondary 5V-usb source in only used during maintenance…
Part Number: TPS54331 Hi,
I want to perform some load transient simulations and play with overshoot/undershoot compensation techniques.
I am not limited to use the mentioned TPS54331, any other buck converter will be fine. I intend to use QSPICE as a…
Hi Meera,
I tried the email address twice but still can't deliver the message.
I've modified a lib file and it works on Pspice for TI.
Please help to check this simulation file firstly, thank you!
