UCC28750 Current-Mode Flyback Controller

Texas Instruments UCC28750 Current-Mode Flyback Controller is a highly integrated current-mode, continuous-conduction-capable, PWM controller optimized for high performance, low standby power, and cost-effective offline flyback converter applications using an optocoupler. During light-load conditions, the device enters frequency foldback and burst modes, improving light-load efficiency. The burst-mode algorithm used in UCC28750 controls the minimum effective switching frequency to prevent audible noise during light-load conditions. Frequency dithering improves EMI performance and is active in normal frequency foldback and power boost operations.
