LM5119 Wide Input Range Dual Synchronous Buck Controller

The LM5119 device 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 using an emulated current ramp. Current mode control provides inherent line feedforward, cyc.
