Product Overview: UCC28515DWR from Texas Instruments

The UCC28515DWR is a versatile and efficient power management integrated circuit (IC) from Texas Instruments, designed to facilitate the creation of high-performance power supplies with power factor correction (PFC). This advanced IC combines a PFC controller and a PWM (Pulse-Width Modulation) controller into a single compact package, specifically the 20-pin SOIC (Small Outline Integrated Circuit) with a wide body. It is engineered to cater to a broad range of applications, including but not limited to telecommunication equipment, servers, and industrial systems, where energy efficiency and reliability are paramount.

The UCC28515DWR offers a unique set of features that enhance its functionality and flexibility. One of its key attributes is the ability to operate in both Continuous Conduction Mode (CCM) for the PFC stage and Critical Conduction Mode (CrCM) for the PWM stage, allowing for optimized performance across different load conditions. This dual-mode operation helps in achieving high power factor and low total harmonic distortion, which is essential for meeting stringent energy regulations.

With a wide operating voltage range, the UCC28515DWR is suitable for universal AC input voltages (85V to 265V), making it a versatile choice for global applications. The device also features programmable soft-start functionality, which minimizes inrush current during startup, thereby protecting the components and extending the longevity of the power supply.

Furthermore, the UCC28515DWR includes a range of protection features to safeguard against abnormal operating conditions. These include over-voltage, over-current, and over-temperature protections, as well as brownout protection. Such features ensure that the power supply operates reliably and safely, even under fault conditions.

The integration of PFC and PWM controllers into a single IC not only saves board space but also simplifies the design process, reducing time-to-market for new products. The UCC28515DWR is a testament to Texas Instruments' commitment to providing innovative and high-quality components for efficient power management solutions.
