LM5141/LM5141-Q1 Synchronous Buck Controllers

Texas Instruments LM5141/LM5141-Q1 Synchronous Buck Controllers are intended for high voltage wide VIN step-down converter applications. The control method is peak current mode control. Current mode control provides inherent line feed-forward, cycle-by-cycle current limiting, and ease of loop compensation. The LM5141 features slew rate control to simplify compliance with EMI requirements. The device has two selectable switching frequencies (2.2MHz and 440kHz). The LM5141 operates in skip cycle mode for improved low power efficiency in light or no-load conditions. This controller has a high voltage bias regulator with an automatic switch-over to an external bias to reduce the I_Q current from V_IN. Additional features include frequency synchronization, cycle-by-cycle current limit, hiccup mode fault protection for sustained overload, and Power Good output. The Texas Instruments LM5141-Q1 devices are AEC-Q100 qualified for automotive applications.
