Cycle by cycle current limiting

WebYou say that if you run in voltage mode, the transformer will saturate. You also say the cycle by cycle current limiting prevents transformer saturation. I have been running a 1500 W design now, in voltage mode, without a blocking cap. I had one in there but took it out because the UCC28950 has current limiting even while operating in voltage mode. WebThe LM5121 is a synchronous boost controller intended for high-efficiency, high-power boost regulator applications. The control method is based upon peak current mode control. Current mode control provides inherent line feed-forward, cycle-by-cycle current limiting and ease of loop compensation. The switching frequency is programmable up to 1 MHz.
