The UCC2808AD-2G4 is a monolithic integrated circuit that provides high-performance buck and boost DC-to-DC voltage regulation. It is a highly versatile switch-mode power regulator controller with a wide range of applications including point-of-load and intermediate bus converters, automotive DC-DC converters, and solar micro-inverters.As a buck-type voltage regulator, the UCC2808AD-2G4 is designed to accurately control an output voltage by pulsing the current it passes through a load. This pulse modulation works by switching the current on and off at a certain frequency. The controller measures the output voltage, adjusts the frequency of the pulses, and adjusts the current it passes through the load. When the control of the frequency pulses is done properly, it ensures the output voltage remains stable. When the UCC2808AD-2G4 is used as a boost regulator, it controls output voltage by modulating the duty cycle of the pulses. This can be done either with a fixed frequency or with variable frequency regulation.The UCC2808AD-2G4 is a high-efficiency DC-DC switch-mode controller built with a number of improvement and protection features. The controller includes an internal on-time generator which can be user-programmed to optimize the operating frequency based on the system\'s needs. There is also an over-current protection feature which ensures the system is protected from accidental overloads.The controller supports wide input voltage range from 5.0V to 18V, and supports both synchronous and non-synchronous operation. Synchronous operation helps reduce losses in power conversion, which leads to improved efficiency and lower costs. The UCC2808AD-2G4 also features Soft Switching, which reduces system noise and transient voltage. Overall, the UCC2808AD-2G4 is a versatile and high-performance DC-DC switch-mode controller with a wide range of applications. Its advanced protection and efficiency features make it an excellent choice for point-of-load and intermediate bus converters, automotive DC-DC converters, and solar micro-inverters.The specific data is subject to PDF, and the above content is for reference
