Other Parts Discussed in Thread: LM3429
My client reported that their switching frequency would under certain circumstances change from 400Khz to half of 200Khz. I directly ask the customer to measure the inductor current and Vgs, and I see that Vgs has this kind of waveform when something goes wrong.
Have you ever encountered this problem? In which direction can I suggest customers to start looking for?
