    Description

    The LM25119 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, cycle-by-cycle current limiting and ease of-loop compensation. The use of an emulated control ramp reduces noise sensitivity of the pulse width modulation circuit, allowing reliable control of very small duty cycles necessary in high input voltage applications. The switching frequency is programmable from 50 kHz to 750 kHz. The LM25119 device drives external high-side and low side N-channel MOS power switches with adaptive dead-time control. A user-selectable diode emulation mode enables discontinuous mode operation for improved efficiency at light load conditions. A high voltage bias regulator with automatic switch-over to external bias further improves efficiency. Additional features include thermal shutdown, frequency synchronization, cycle-by-cycle and hiccup mode current limit and adjustable line undervoltage lockout. The device is available in a power enhanced leadless 32-pin WQFN package featuring an exposed die attach pad to aid thermal dissipation.
