Part Number: LM51551-Q1 Hello,
I am currently investigating LM51551-Q1 for an application.
When studying Application Note SNVA866 I was wondering about Diode D3.
You are writing this is an design with attempted operation in CCM. Therefore I would assume…
Hello,
Thank you for the feedback. As you plan to have a pretty low input voltage, I would suggest to use the approach with the charge pump, like in figure 10-8 . At this link you can find a reference design with a similar device to the LM51551 ( https…
