LM5117 Datasheet (Texas Instruments) - Wide Input Range Synchronous Buck Controller

LM5117, Wide Input Range Synchronous Buck Controller

The LM5117 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-bycy
