LM5140QRWGTQ1 Information
- LM5140-Q1 Dual Low Iq Synchronous Buck Controller
- Texas Instruments LM5140-Q1 Dual Low Iq Synchronous Buck Controller is intended for high voltage wide VIN step-down 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 2.2MHz or 440kHz 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 synchronous buck controllers are AEC-Q100 qualified for automotive applications.
