LM5148/LM5148-Q1 Buck DC/DC Controller

Texas Instruments LM5148/LM5148-Q1 Synchronous Buck DC/DC Controller is an 80V, ultra-low IQ controller for single-output, high-current applications. The controller uses a peak current-mode control architecture for a fast transient response, easy loop compensation, and excellent load and line regulation. The LM5148 can be set up in ideal-phase mode (paralleled output) with accurate current sharing for high-current applications. It can operate at input voltages as low as 3.5V, at nearly 100% duty cycle if needed.
