I simulated the TPS54383 using the schematic on page 33 of its datasheet. However there is a significant ripple in the output voltage - 500mV for the 3.3 output and 800mV for the 5V output. I know that there is a restriction on the max output capacitance but any way I can reduce this ripple? This ripple is non-existent when I simulated a variant of this circuit that has 12V and 5V outputs. I've attached the 5V and 3.3V output circuit and the waveforms here.
