Hi All,

I got confused in circuit analysis. I have attached circuit here for the reference. (It is LT3798.).
I want to know what is the function of R3 and R4 which goes into the "VIN_Sense"? And also function of R7 and R8 which goes into the "VIN through D3 (also wanted to confirm that D3 is just rectifying signal which is coming from Bridge Rectifier?)

Resistors R5 and R6 are making "resistor divider" for pin "EN/UVLO". Correct?

Basically I want to know, what is the final voltage that goes into this chip? And also it will be great if someone tell me output after BR1 and D3.

Thank you very much in advance.

You have not read the datasheet for LT3798 to know what is meaning of each chip pin. Study it and you will find answers to all your questions by yourself.

Hi Borber,
I read but i was not clear enough for those resistors.
Thank you.
