Monolithic Power Systems, Inc. Voltage Regulators - Linear + Switching NB679AGD-P

The NB679AGD-P is a high-frequency synchronous step-down converter designed to provide a fixed output voltage of 5.1V with a continuous output current of 8A and a peak output current of 10A. It operates efficiently over a wide input voltage range of 5.5V to 28V, making it suitable for various applications including laptop computers, tablet PCs, and networking systems. The device features adaptive constant-on-time control for fast transient response and a DC auto-tune loop for improved load and line regulation. It includes a built-in 5V LDO capable of supplying 100mA for external peripherals and incorporates multiple protection features such as overcurrent protection, overvoltage protection, undervoltage protection, and thermal shutdown. The NB679AGD-P is packaged in a compact QFN-12 (2mm x 3mm) format, requiring minimal external components for operation.
