Hello,
I have met difficulty evaluating the performance of the LT1328 based on different rail filtering parameters. In my simulation model, I emulate noise on the +5V rail and try to filter it using decoupling capacitor and a ferrite bead. The simulation results are disastrous: the output always experiences a data flow interruption for different L1/C4 parameter combinations. It also varies depending on the maximum .tran step.
Any ideas ?
