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 cycle current limiting and ease of loop compensation.
