Product Overview
FAN251040 is a highly efficient synchronous buck regulator with digital interface, capable of operating with an input range from 4.5V to 18V and supporting up to 40A load currents. The FAN2510xx utilizes a fixed frequency voltage mode control architecture to provide a synchronized constant switching frequency while ensuring fast transient response. Switching frequency and overcurrent protection can be programmed to provide a flexible solution for various applications. Output overvoltage, undervoltage, overcurrent, and thermal shutdown protections help prevent damage to the device during fault conditions. Typical applications include server and desktop computers, notebooks, gaming, telecommunications and high density power solutions.
