Since this error is happen by chance or say system instable, I have re-work on the loop circuit value
but it not helping, the above waveform still happen by chance. (e.g. 2~3 times out of 10 enabling)
Here is my loop calculation table
7206.TPS40428…
Part Number: TPS40322 power supply block with TPS40322 was designed in accordance to the Application Note as well as the Loop Stability calculator file.
PDFs are attached. Can we count on an stable operation with the chosen values of the components…
Part Number: TPS40428 Hi Sir,
I am working with TPS40428 on my system, it is working and output 1V to FPGA constantly.
But at the same time the PMIC have a 520mV Vripple output and affecting other voltage rails, may causing failure on DRAM calibration…
Part Number: TPS40428 Hi Ti team,
I have build a board with TPS40428 and 2x CSD95378B for evaluation, using 12V input to provide 1V output, design reference from PMP9444
but now my system have 2 issues
1/ OVF are easily triggered when enable TPS40428…
Part Number: TPS546C20A Other Parts Discussed in Thread: TPS546C23 , I am facing two issues with TPS546C20A on a single phase design.
Input: 12V
Output: 0.845V 30A
Issue 1: On the measured loop gain, at the low frequency region (1kHz to 4kHz,…
Hi Jospeh,
Thanks for your inputs.
I have updated the power calculator and selected suitable Feedback and compensation network. Please review the schematics and power calculator bode plots and provide if any review comments. I would like to release…
Hello Anthony,
Please provide the updated TPS40KType spreadsheet that you used prior to making the last recommendations for the compensation network values.
Please see attached.
