NB679 28V, Low Iq, High Current, Fixed 5V-8A Synchronous Buck Converter with 100 mA LDO DESCRIPTION The NB679 is a fully integrated, high-frequency, synchronous, rectified, step-down switch-mode converter with a fixed 5 V output. It offers a very compact solution to achieve 8 A continuous output current and 10 A peak output current over a wide input supply range with excellent load and line regulation. The NB679 operates at high efficiency over a wide output current load range based on MPS proprietary switching loss reduction technology and internal low Ron power MOSFETs. Adaptive constant-on-time (COT) control mode provides fast transient response and eases loop stabilization. The DC auto-tune loop provides good load and line regulation.
