Part Number: TPS40101 Hi expert,
For most of part, the ss voltage will greater than comp voltage during soft start, While the customer found that the comp voltage is greater than SS voltage. Is it normal for TPS40101?
Hi
I have a simple question about Vssos on the datasheet.
The Vssos means 350mV in the following block?
If it so, the start point of Vout soft-start varies between Vss=300mV~800mV. Is that correct?

Hi MD,
I don't think we have the applicaiton note for the TPS40101 over current protection design.
I would suggest to design for the worst - make sure all the part could deliever full-load current for all the application temperature. Therefore, based…

TPS40101 doesn't show the thermal performance on data-sheet but we need below parameters.
Please help to provide.

If they do not need PMBus, there are a number of possible solutions they could consider, depending on the application needs.
TPS40101 is a voltage mode control controller capable of operating upto 1MHz switching frequency with drivers…
akircan,
I understand your concern, however it is not necessary to select a 40A inductor.
1) Under heavy load, the sensing FET will heat up quickly, increasing its Rdson. The Rdson can increase upto 40%, providing a significant increase in…
Part Number: TPS40422 Tool/software: Hi expert,
Customer used TPS40422 for 12Vin to 0.88Vo/40A and use the calculation tool for compensation but find the phase/gain margin is not good.
Would you please advise how to adjust the stability?

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

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…
