3.1 Switching

PMP31263 Switching Waveform (10µs/div)
  • CH2: DC-coupled switch node voltage [scale: 10V/div, 10µs/div, 500MHz bandwidth]
  • Output current: 20A
Figure 3-1 Switching Waveform (10µs/div)

The waveform in Figure 3-2 is captured with the same settings as in Figure 3-1 only the time base is different.

PMP31263 Switching Waveform (100ns/div)
  • CH2: DC-coupled switch node voltage [scale: 10V/div, 100ns/div, 500MHz bandwidth]
  • Output current: 20A
