Part Number: UCC2818A-Q1 Hi team,
At low line, customer found small current distortion while input voltage come across zero both on their board and our EVM, have you experienced with this phenomenon?
(Green is input current, yellow is input voltage,…
Hi Pol,
I am not sure that the UCC2818A-Q1 is suitable for this application.
Therefore I will limit my response to your first question.
You can design a 12V output flyback type pfc with a transition mode(TM) pfc controller but I am not aware of any such…

Part Number: UCC2818A Hello.
I made a 1200W power supply using UCC2818A. We conducted tests to confirm the performance of this power supply. Noise tests were performed. UCC2818A stopped its operation. At this time, VREF pin = 0 V. It will not recover unless…
Part Number: UCC2818A Hello. I have a question about UCC 2818A.
Q1 Kis the multiplier gain constant. What does K = 1 / V mean? Q2 datasheet P15 I think that Figure 5 is the value of each part of the circuit at K = 1. When considering K = 1.5, which part of the…
