As shown in the voltage waveform VSW of the switching node SW of the synchronous buck converter, Vin=19V, Vo=1V, fsw=900k, L=250nH, under the premise of ensuring the correct measurement method, it can be found that the voltage of the switching node VSW is On the falling edge, a negative voltage peak will appear, and the negative voltage peak is -6.9V.
The parasitic inductance of the power MOSFET including PCB wiring or copper is shown in the parametric model, where TH and TL are the upper and lower tubes of the BUCK converter, respectively, and LD-L1 is the lead from the drain D pin of the lower tube to the output inductance. Inductance, LS-L1, LS-L2 are the lead inductance from the S pin of the lower tube source to the negative end of the input capacitor.
