LM5149/LM5149-Q1 Buck DC-DC Controller

Texas Instruments LM5149/LM5149-Q1 Synchronous Buck DC-DC Controller is an 80V, ultra-low IQ synchronous buck DC/DC controller for high-current, single-output applications. The controller uses a peak current-mode control architecture for easy loop compensation, fast transient response, and excellent load and line regulation. The LM5149/LM5149-Q1 can be set up in dual-phase mode with accurate current sharing for high-current applications. The device can operate with VIN as low as 3.5V, at nearly 100%, if needed.
