Hi,
I use TPS61021DSGT for our design. But I got a confusion about the reference design.
From data sheet,
If the effective output capacitance is less than 40 μF, I can got the C3 value use equation 10.
This is what I web bench's result.
Input rang：1-1.4VDC
Output: 1.8VDC
max current: 30ma
normal current: 3ma
Rfbt =127k
So the Cff = 1/(2*pi*127k*50k) = 25pf, but bench give me suggestion is Cff=56pF.
Thanks!
