Hello to all and thank you fin advance for your support.
We are designing a ultra low PSU using the ucc28740
Unfortunately we are seeing noise at 5.5K and 17khz at about 500uV. We found the feedback network to be the one responsible for it (by changing the feedback points the noise disappears and reapers at different frequencies) . We took a look at the calculation and feedback network seems to be badly calculated and unsuitable for the ucc 28740
Can you please assist with the correct calculation on type 2 compensator ? We tried the online tool but its not suitable for our low noise PSU
thank you
