LM5141QRGERQ1 Information
- 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 the compliance with EMI requirements. The device has two selectable switching frequencies (2.2MHz and 440kHz). In light or no-load conditions, the LM5141 operates in skip cycle mode for improved low power efficiency. This controller has a high voltage bias regulator with automatic switch-over to an external bias to reduce the IQ current from VIN. Additional features include frequency synchronization, cycle-by-cycle current limit, hiccup mode fault protection for sustained overload, and power good output. The LM5141-Q1 devices are AEC-Q100 qualified for automotive applications.
