Hello Armin,
The TPS54540-Q1 is more sensitive to noise than the TPS54540B-Q1. Since the part is not shutting down due to heat, noise is the most likely problem. Three approaches to reducing noise sensitivity are:
1) Use the TPS54540B-Q1.
2) Careful…
Hello Vito,
The large input loop – see figure below – combined with the parasitic inductance of the diode is causing a noisy switching waveform. This can be seen by undershoot when the switch node falls in the waveforms that you provided. Even with…
