Hi team,
Our customers will begin to design from using the LM25011.
There is a question regarding the current limit especially when looking at the data sheet.
#1
Is the function of current limit same as setting On time to 40%?
#2
Typical ON time of the LM25011 at the current limit is 100ns in the data sheet, but there are not written minimum and maximum on time.
How much will the on time 40% at the current limit fluctuate?
Because I think that the peak current during current limit is determined by the on time, I would like to know.
#3
What does it mean minimum current limit threshold written in datasheet page 18 Rs section.
Does the threshold of the current limit change?
#4
It is written to use low ESR ceramic capacitors, please tell me specific value.
#5
Although it is written to use a Schottky diode in the section of DI, I do not know how influence will be caused by ultra fast recovery diode.
Is there any document that I can understand?
Best regards,
Tomoaki Yoshida
