LM25145RGYR General Description

The LM25145RGYR is a versatile synchronous buck controller meticulously crafted to regulate power in environments with high input voltage variability. Its robust design minimizes the requirement for external surge suppression components, ensuring reliability in challenging conditions. With a minimum high-side switch on-time of 40 ns, it facilitates seamless step-down conversion, efficiently transforming a 24 V nominal input to lower voltage rails, thus simplifying system architecture and reducing costs. Its ability to operate during input voltage dips as low as 6 V, with nearly 100% duty cycle if necessary, makes it an ideal choice for demanding applications such as industrial control, robotics, data communications, and RF power amplifiers
