Hi,
I asked the maximum rating on the negative side of the SW pin in the following thread.
I understand that the inductor current flows during the dead time period.
This time, I would like to ask about that dead time.
Attach the measurement waveform. Measured waveform of SW pin.
Looking at this waveform, the negative voltage continues for about 30 ns. Is this a dead time?
If this period is dead time, why does it continue for 30 ns?
In addition, although this period of 30 ns is about -0.7 V, is it OK to think that there is no problem?
(Measurement condition)
VIN: 13 V
VOUT: 2.5 V
IOUT: 200 mA
Best Regards,
