Part Number: UCC28633 I am Keshab I develop a smps with ucc28633 as per web design tool also transformer. Also follow all the recommendation. input is universal and output is 24v/5a. I faced starting problem. UCC28633_120X75.pdf
Hello Mike,
Thank you very much for your input. Sorry for my delayed response. The problem is sorted out as per your input. The controller was going in Over Current fault mode. The snubber and the value of Current Sense resistor had to be altered to…
Part Number: UCC28633 Other Parts Discussed in Thread: UC2844 Hi,
My customer check with me if this device can support to set the UVLO to 150V. if not, could you please recommend another device which can meet this requirement? thanks.
