Other Parts Discussed in Thread: LM5575
Hi,
About the chip LM5575-Q1, I have some question. At the moment of 24V power on, the chip have a 8V peak voltage ,about 10ms, but it should be 5V. When I change the ceramic capacitor C48 from 100nF to 10nF, it become normal. I want to know the reason. Give me a hand ,thanks.
