Hi,
We are considering using TPSM82821 to replace some enpirion parts that are EOL. The TPSM82821 has a max output capacitance of 47uF, which is similar to the enpirion EP53A8xQI max of 60uF. However, we also have additional capacitance at the load which is seperated from the module through a ferrite bead. The enpirion datasheet states this is ok:
"Additional bulk capacitance for decoupling and bypass can be placed at the load as long as there is sufficient
separation between the VOUT Sense point and the bulk capacitance. The separation provides an inductance
that isolates the control loop from the bulk capacitance."
can we do something similar with the TPSM82821, with local vout decouple <47uF, but then with additional >100uF bulk near the load separated by a ferrite bead?
does the provided PSPICE model accurate for simulating stability for such a configuration? The idea is we would follow this method https://www.analog.com/en/technical-articles/ltspice-basic-steps-in-generating-a-bode-plot-of-smps.html. However, we've had issues before with ltspice model before where the simulation did not match bench results and the response we got from ADI was the response was not accurate in the provided spice model
