The NB679A is a fully integrated, high- frequency, synchronous, rectified, step-down, switch- mode converter with a fixed 5.

Product Detail

The NB679A is a fully integrated, high- frequency, synchronous, rectified, step-down, switch- mode converter with a fixed 5.1V output andwith low- power mode voltage scaling. It offers a very compact solution to achieve an 8A continuous output current and a 10A peak output current over a wide input supply range with excellent load and line regulation. The NB679A operates at high efficiency over a wide output current load range based on MPS proprietary switching loss reduction technology and internal lLow Ron pPower MOSFETs. Adaptive cConstant-oOn-tTime (COT) control mode provides fast transient response and eases loop stabilization. The DC auto- tune loop provides good load and line regulation. NB679A also provides a fixed 5V LDO, which can be used to power the external peripheries. Full protection features include OC lLimit, OVP, UVP, and thermal shut down. The converter requires a minimum number of external components and is available in a QFN-12 2mm x 3mm packages.
