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?
When SS pin voltage is lower than offset voltage, the COMP stay at 0V. When SS pin voltage is larger than offset voltage, the COMP starts to rise up from 0V. It will take some time for COMP voltage rise from 0V to PWM ramp valley. Before COMP…
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?

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.
