TEXAS INSTRUMENTS UCC25705 UCC25706 UCC35705 UCC35706 handbook
The UCC25705, UCC25706, UCC35705, and UCC35706 devices are 8-pin voltage mode primary side controllers designed for high-speed operation greater than 4 MHz. They feature an integrated oscillator with voltage feed-forward compensation to improve converter performance and maintain constant frequency over the full input voltage range. A typical current sense to output delay of 25 ns provides fast response to overload conditions.
