The LM5141-Q1 is a synchronous buck controller, 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-Q1 features slew rate control to simplify the compliance with CISPR and Automotive EMI requirements.
●The LM5141-Q1 has two selectable switching frequencies: 2.2 MHz and 440 kHz. Gate Drivers with Slew Rate Control that can be adjusted to reduce EMI.
●In light or no-load conditions, the LM5141-Q1 operates in skip cycle mode for improved low power efficiency. The LM5141-Q1 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.
