UCC28512N Application Field and Working PrinciplePower Factor Correction (PFC) is an electronic technology for ensuring a consistent and efficient power supply for modern electrical applications. An important part of the PFC process is the provision of a Power Factor Controller (PFC) which optimises the Voltage Correction Circuit (VCC) and the current waveform. The UCC28512N is a powerful PFC controller used for commercial and residential applications alike.The UCC28512N is a single phase, PFC controller from Texas Instruments and is part of the UCC Series of low-power PFC controllers. Specifically, the UCC28512N is a step-down converter. It is used to adjust the power factor of a power supply to ensure that it meets the requirements of the National Electrical Code (NEC). The UCC28512N is designed to meet stability and performance requirements of commercial applications, but can also be used in residential applications.The UCC28512N provides two phases, On-Time and Off-Time, of power factor control, which are optimized for high efficiency and fast transient response. In the On-Time phase, the power supplies are switched at discrete frequencies providing maximum efficiency, while the Off-Time phase is used to reduce current harmonics and improve power factor. The UCC28512N also implements many on-chip proof-of-concept features, including frequency dithering.The UCC28512N uses a voltage-mode control loop for phase-shifted PFC (PSPFC) control, which allows the system to use either of two pulse-width modulation (PWM) control modes, single-phase Current Mode Control (CMC) or two-phase Voltage Mode Control (VMC). The UCC28512N has an integrated, wide-range, copper-based gate driver with over 1.2 A peak output to ensure that the power components can safely switch at high frequencies and deliver high efficiency.The UCC28512N features a comprehensive diagnostic system including short circuit protection, over-temperature protection, over-voltage protection and under-voltage protection. Additional features include an internal soft-start, open-loop and close-loop operation, regulation voltage accuracy of 1 %, and line-current sensing up to 100 A.The highly optimized UCC28512N is particularly useful for cost-sensitive applications, as it offers an attractive option for high-efficiency, low-cost, and fast-transient-control applications. The high degree of integration and low quiescent current ensures that the UCC28512N can fit into small form factors and high-volume applications.In conclusion, the UCC28512N is a specialized PFC controller with a wide range of applications. It can be used as a commercial or residential device offering high power factor, low power losses and high efficiency. The wide array of features provided by the UCC28512N, such as diagnostic system, soft start, over and under voltage protection, and wide range gate driver, make it a versatile device. Furthermore, the integrated, copper-based gate driver makes the UCC28512N ideal for applications with a low electrical noise requirement.
