Dear, Sir.
According the product brief, fSW max = 2,000kHz.
1) So, I would like to make sure how many switching cycles would be needed
for the proper iLED regulation under PWM dimming by external NMOS, theory-wise?
Best Regards,

Dear, Sir.
My customer want to double-confirm PWM dimming range capability of
LM3409-Q1.
The datasheet defines 10,000 : 1 on its features and describes a design
example of fSW=500kHz.
I suppose the dimming range would be related to fSW.
1. So, I would like to know the highest capable fSW of LM3409-Q1.
I am hoping to get your advice.
Best Regards,
H. Sakai
