The LM5163QDDARQ1 synchronous buck converter is designed to regulate over a wide input voltage range, minimizing the need for external surge suppression components. The minimum controllable on-time of 50ns enables a large step-down ratio, enabling direct step-down conversion from a nominal 48V input to a lower voltage rail, reducing system complexity and solution cost. The LM5163-Q1 is capable of continuing operation at near 100% duty cycle as needed when the input voltage drops to 6V, making it ideal for high-performance 48V battery automotive applications and MHEV/EV systems.
