LM5146/LM5146-Q1 100V Synchronous Buck Controllers

Texas Instruments LM5146/LM5146-Q1 100V Synchronous Buck Controllers regulate from a high input voltage source or an input rail subject to high voltage transients. This feature minimizes the need for external surge suppression components. A high-side switch minimum on-time of 40ns 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 solution cost. The Texas Instruments LM5146/LM5146-Q1 continues to operate during input voltage dips as low as 5.5V, at nearly 100% duty cycle if needed. This feature makes it an excellent choice for high-performance 48V battery automotive applications, ADAS (surround view ECU), and HEV/EV systems.
