Power Factor Correction (PFC) is a technique used for improving the efficiency of AC to DC power converters. The goal of PFC is to increase efficiency by reducing the amount of current used in the conversion process. This reduces the cost of energy consumption and makes the AC to DC converter more efficient overall.
The UCC28063DR is a nonisolated, peak-current-mode PFC controller designed to operate in power factor correction (PFC) circuits. The UCC28063DR can operate in quasi-resonant flyback topologies as well as other PFC power converter topologies such as buck/boost and active clamp. The UCC28063DR provides integration of both the PFC and soft-start circuit. It also includes lightweight over temperature and over current protection.
The UCC28063DR receives the rectified AC input and regulates the current to a preset level by controlling the primary windings of the PFC main transformer. The UCC28063DR utilizes a phase-shift control technique to minimize conduction losses while ensuring a constant current input into the load. This characteristic of the UCC28063DR makes it ideal for power supplies with low power consumption that require high efficiency and robust PFC performance.
The UCC28063DR is designed for enhancing the power factor conversion of a power supply system, resulting in improved power quality. This controller is designed to provide an accurate current-mode control, allowing for a wide current range with fast transient response. It is also designed to help reduce output impedance, providing improved performance in noise sensitive applications. The device is capable of detecting and responding to transient disturbances, which helps maintain optimal power factor performance.
The UCC28063DR provides a wide range of protections and diagnostics, helps reduce system noise in sensitive applications, and has built-in soft-start. The controller also offers the ability to switch the PFC circuit to discontinuous mode (DCM) operation, minimising load losses and improving efficiency. This device is able to provide a pre-bias voltage supply to support a wide range of input voltages, including very low input voltage conditions.
In addition to the core device features, the UCC28063DR includes a set of digital and analog interfaces to enable superior control and monitoring. An integrated enable/disable control pin allows the device to be turned on and off through external connections. An external resistor and capacitor provide full protection from line and load transients, limiting the cost and complexity of protection circuitry. Digital and analog status feedback, reporting thermal and fault information, is also available to facilitate efficient code and system development.
The UCC28063DR is an ideal solution for improving the power conversion efficiency in space-constrained AC/DC power supplies. The device\'s high performance and robust features, combined with small chip size and fast response, make it suitable for a wide range of PFC applications. This controller provides reliable, low-cost power factor correction, enabling efficient and cost effective power supplies.
