Switching

Switching behavior is shown in the following figures. Each waveform reflects the following parameters:

  • Vds_low side: drain source voltage of low-side switch Q2
  • Vsw: switching node voltage connecting to Q1 drain refer to primary ground
  • Vds_high side: drain source voltage of high-side switch Q1
