TEXAS INSTRUMENTS
The LM5116MH/NOPB 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-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 operating frequency is programmable from 50kHz to 1MHz. The LM5116 drives external high-side and low-side NMOS power switches with adaptive dead-time control. User-selectable diode emulation mode enables discontinuous mode operation, for improved efficiency at light load conditions. A low quiescent current shutdown disables the controller and consumes less than 10µA of total input current. Emulated peak current mode Drives standard or logic level MOSFETs Robust 3.5A Peak gate drive Optional diode emulation mode Precision 1.5% Voltage reference Programmable current limit Programmable soft-start Programmable line undervoltage lockout Automatic switch to external bias supply Thermal shutdown Green product and no Sb/Br Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
