Texas Instruments LV5144 95V Synchronous Buck Controller regulates from a high input voltage source or an input rail subject to high-voltage transients, minimizing the need for external surge suppression components. A high-side switch minimum on-time of 45ns gives large step-down ratios, enabling the direct step-down conversion from a 48V nominal input to low-voltage rails for reduced system complexity and design cost. The Texas Instruments LV5144 continues to operate during input voltage dips as low as 6V, at nearly 100% duty cycle if needed, making an excellent choice for high-performance industrial controls, robotics, datacom, and RF applications.
