    TPS65400 on PYNQ-Z1 board

    Hi, The values obtained by using the datasheet formulas depend on a few variable parameters you are considering for your design. Some of these must be set/programmed before building the supply. The switching frequency, the internal reference voltage, the lowest load resistance (highest load current) and the filtering capacitor ESR will all influence the calculations directly. The final values may also suffer adjustments during validation, depending on the measured real phase margin and dynamic performance. Regards, Gabor

    TPS65400 on PYNQ-Z1 board

    Hi @lowuze, a little late with an answer but if you still haven't found your solution you might want to look into the TPS65400 datasheet offered by TI. You can find it here http://www.ti.com/lit/ds/symlink/tps65400.pdf Beginning with page 23 you'll find the small signal equivalent model of the regulator and the equations used to determine component values in the feedback and compensation networks.
