Hi Eddie,
Thank you for the scope pictures. May I guess those were taken without 1uF SS capacitor, right? The ss voltage does not look correct in the first page, for being much faster than the internally fixed ~6ms, not to mention with either 0.22uF or…
Hi Ravindran,
Thank you for designing with the LM5185. I reviewed your calculator file, it is looks okay. Some suggestions:
DCLAMP choose 36V, so you can use 100V MOSFETs.
RFB should be 255k, not 284k.
Reserve the option of using external SS by adding…

Part Number: LM25184-Q1 Other Parts Discussed in Thread: LM25184 I am designing a flyback converter using LM25184-Q1. During efficiency calculation, I am not able to figure out how to calculate the switching loss of the MOSFET integrated in the IC. I…
Part Number: LM25184 Other Parts Discussed in Thread: LM5122 Hi
I have -15V supply. I want to use LM25184 with that supply as GNV as -15V terminal and 0V terminal as Vin.
Will LM25184 work in this way?
Part Number: LM25184-Q1 Other Parts Discussed in Thread: LM25184 Hi Expert, What will be the switching frequency selection criteria?. We have three 12V loads of following power ratings 1W,1W,1,3W with input voltage 9-16V .Is there any specific criteria…
Part Number: LM25184 Other Parts Discussed in Thread: LM25017 The datasheet states 1.5% accuracy.
I believe with output of ~ 4V, that's about 60 mV tolerance.
I need to double or better the accuracy. Any way?
Also, can Vout be adjusted during operation…
