Hello,
Iam designing an smps based on the attached schematic.
My requirement is,
- The input voltage for the smps is 230
- The output voltage should be 12V DC.
- I have to show a constant 12V DC for different inputs like 180v, 190v,.... 250V.
I have tested the SG3525A on a bread board. It is OK with the two complementary pulse sequences.
How can i connect the output sample to the IC to get my requirement.
I have seen some circuits in the internet. But different circuits had different techniques.
By seeing the block diagram in the datasheet, I understood that the feedback signal should adjust the reference voltage which compares with the sawtooth.
How can i implement this???
I want some detailed explanation please...
thankyou
