LM5140RWGEVM Part Information
The LM5140-Q1 is a dual synchronous buck controller intended for high voltage wide VIN stepdown converter applications. The control method is based on current mode control. Current mode control provides inherent line feed-forward, cycle-by-cycle current limiting, and easier loop compensation. The LM5140-Q1 features adjustable slew rate control to simplify compliance with the CISPR and automotive EMI requirements. The LM5140-Q1 operates at selectable switching frequencies of 2.2 MHz or 440 kHz with the two controller channels switching 180º out of phase. In light or no-load conditions, the LM5140-Q1 operates in skip cycle mode for improved low power efficiency. The LM5140-Q1 includes a high voltage bias regulator with automatic switch-over to an external bias supply to improve efficiency and reduce input current. Additional features include frequency synchronization, cycle-by-cycle current limit, hiccup mode fault protection for sustained overloads, independent power good outputs, and independent enable inputs.
