Hello Team,
I got a question about frequency variability.
When COMP/FSET connected VIN or GND directly, the Fsw variability is +/-10%.
When using using a resistor, the Fsw variability is 18%!
Why does the variability get wide just adding resistor?
In other words, if the resistoer has no variability, the frequency variability still keep +/-10%?
