Dear *,

I have some questions regarding the stability of TPS62067-Q1:

First this is my configuration:

Iout is from 100mA to 350mA

1) What is the impact of the capacitance that is after Ferrite bead on DCDC stability ?

2) Is there a way to calculate the cff without to measure the crossover frequency?

3)Does the Equation 6 on page 14 in DS apply also to PFM mode?

Best Regards.
