Hi, Sir
1. The calculation is correct.
Rc value determines the bandwidth of loop, but when bandwidth is large, it is very sensitive to noise when layout is bad, so i suggest reducing its value.
2. After changing, suggest probe some waveforms:…
Part Number: TPS65279 Other Parts Discussed in Thread: TPS65270 , Hi team,
my customer and i imported the PSpice model from the product folder into PSpice and tried to run the simulation.
I get an error in the output window shown below.

Hi Doug,
Thank you for your interest in the device and WEBENCH. We do not have the WEBENCH support for TPS65279 in our current pipeline. We will forward your interest to the corresponding product support team. Please post any specific design help…
Part Number: TPS65279 The datasheet shows 95% efficiency for 12V to 5V conversion. Is this for a single phase design? What is the expected efficiency for a 2-phase configuration on this part?
Any input is appreciated!
Thanks,
Jack

Part Number: TPS65279 Hello, two questions below:
1. 100% duty cycle means this device support Vout=Vin=5V if we neglect the very small voltage dropout?
2. About UVLO, there is a Vin UVLO and another Vbootuv. Whichf one will be first triggered?
