UCC28704 Off-Line Flyback Controller

Texas Instruments UCC28704 Off-Line Flyback Controller is a highly integrated, 6-pin primary-side regulated PWM controller. This controller is for designing high efficiency AC-to-DC power supplies with low standby power consumption to comply with global efficiency standards. The controller has ultra-low current consumption at start-up to enable designs with < 30mW no-load input power and save standby mode energy consumption. Intelligent primary-side sensing and control enable 5% output voltage and current control without using an optocoupler or secondary-side feedback circuits. The UCC28704 incorporates an enhanced load transient response technique which helps minimize the output capacitor, reducing the overall system size and cost. The controller also eliminates the need for loop compensation components which simplify the design and debugging process for power supply designers.
