LM5119 Datasheet - National Semiconductor

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.

LM5119 Features

* include thermal shutdown, frequency synchronization, cycle-by-cycle and hiccup mode current limit and adjustable line under-voltage lockout. The device is available in a power enhanced leadless LLP-32 package featuring an exposed die attach pad to aid thermal dissipation. Features

* Emulated pe
