UCC2972N is a lighting solution for ballast and home lighting applications from Texas Instruments. It is designed to provide a simple, cost-effective solution for energy efficient lighting systems.UCC2972N is a DC/DC converter that accepts a wide range of voltage inputs, including universal AC mains. The device is capable of delivering up to 15 A of continuous current to load with a maximum peak current up to 25 A. UCC2972N also includes several features to ensure reliable operation and protect the system from various external hazards. UCC2972N’s application field covers a wide range of lighting systems. It can be used for ballast and home lighting applications such as general illumination, street lighting, commercial lighting, and stage lighting. In addition, UCC2972N can be applied in motion lighting systems such as LED displays, LED channels, LED strips, LED signs, RGB LED lights, LED corridors, LED staircases, LED decorative lights, LED modules, and LED security systems. UCC2972N also can be used in industrial lighting systems such as manufacturing process lighting, agricultural cultivation lighting, office lighting, and medical lighting. With UCC2972N, lighting designers can benefit from fewer components, easier design-in, and smaller form factors. The working principle of UCC2972N is quite straightforward. It consists of a Buck converter, an AC/DC main power supply, and four drivers. The Buck converter works by converting the AC or DC input voltage into a stepped-down DC voltage. This voltage is then delivered to the entire system by means of the drivers. The voltage and current of the input is monitored by the main power supply to ensure that the system is operating safely and efficiently. The four drivers are designed to control the output voltage (Vout) and current (Iout) of the UCC2972N. The driver is responsible for controlling the brightness of the light source. It is regulated by the control signals from the Buck converter, and the applied voltage and current to the ballast. The driver can also provide remote dimming, various dimming curves, constant power devices, thermal protection, and current/voltage adjustment capabilities. The UCC2972N is a powerful and versatile solution for energy efficient lighting system applications. Its wide voltage input range allows it to work in different mains voltages, while the four drivers make it suitable for a variety of lighting applications. Furthermore, its protection features improve the reliability and safety of the system.
