LM5119 Datasheet (National Semiconductor) - Wide Input Range Dual Synchronous Buck Controller

LM5119, Wide Input Range Dual Synchronous Buck Controller

The LM5119 is a dual 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
