LM5116-HT WIDE RANGE SYNCHRONOUS BUCK CONTROLLER

The LM5116 is a synchronous buck controller intended for step-down regulator applications from a high voltage or widely varying input supply. The control method is based upon current mode control utilizing an emulated current ramp. Current mode control provides inherent line feed-forward, cycle by c.
