UCC2817DTR

The UCC2817DTR is a sophisticated and versatile power management integrated circuit (PMIC) designed to offer up to 9.5 A of continuous load current in high efficiency, power factor corrected (PFC) applications. The PMIC is designed to provide a feedback mechanism to monitor input and output voltage, temperature, and current to ensure reliable system operation. It also offers a variety of integrated features to optimize the performance of the power factor corrected system.

The UCC2817DTR is specifically designed to manage the input power line active PFC applications with the power factor correction (PFC) feature. It is able to accurately compensate for input line harmonics and closely track steady state current, actively controlling the active power factor correction loop. The PFC feature minimizes input current distortion, reduces power loss, and improves the overall efficiency of the system. Furthermore, the power factor correction (PFC) feature contributes to enhanced system performance as it eliminates cross-line voltage interference and reduces equipment size.

The UCC2817DTR is designed to offer a true power factor corrected system with flexible operation modes. It offers a digital control loop including a phase-shift control, a digital core, and a digital reference to precisely control the active power factor correction loop. The phase-shift control method enables the UCC2817DTR to provide high efficiency energy conversion with extremely low harmonic content. The digital core provides the UCC2817DTR with the flexibility to quickly adjust the system operation as needed for optimal power factor correction. The digital reference is also adjustable, allowing for improved accuracy and flexibility of operation. These features make the UCC2817DTR an ideal choice for applications requiring true power factor correction.

In addition to the power factor correction features, the UCC2817DTR also offers additional features to optimize system performance. It includes an internal current-limit protection circuit to protect the system from over-current faults. It also offers an adjustable soft-start feature to reduce output inrush current. The UCC2817DTR can be configured to work in either continuous or discontinuous-conduction modes and can be paired with a boost or buck converter topology. Additionally, the UCC2817DTR is designed to provide an adjustable power limiter and allows for the monitoring of system status, temperature, and output overvoltage.

The UCC2817DTR is well suited for a wide range of power factor corrected (PFC) applications, such as power supplies, fans and pumps, lighting, and motor control systems. Its highly integrated features, adjustable power limiter, and versatile operation modes offer reliable and efficient power factor correction. It is a cost-effective solution for a variety of power factor corrected applications requiring high efficiency and good power quality.
