The NB679 is a fully integrated, high-frequency, synchronous, rectified, step-down switch-mode converter with a fixed 5 V output.

Product Detail

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. NB679 provides a fixed 5 V LDO, which can be used to power the external peripheries. Full protection features include OC limit, OVP, UVP, and thermal shutdown. The converter requires a minimum number of external components and is available in QFN 2mm x 3mm package.
