Other Parts Discussed in Thread: LM3424
Hi team,
I did an experiment using LM3424 buck-boost EVM that I removed R6 and then test the GATE and IS waveform. Power on and I found that IS and GATE has the same peak value(nearly 6.9V, equal to VCC) and frequency, their waveform are basically the same.
What I want to know is: Why the IS voltage will be the same with GATE voltage when the NMOS is turned on, rather than VIN after I remove R6?
Thank you
