MPS NB679AGD-Z

Понижающий (Buck) синхронный (1), линейный (LDO) (1)25,1 В, 8 А5,5 В ~ 24 В

Overview

The NB679AGD-Z is a fully integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter with a fixed 5.1V output and 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 NB679AGD-Z 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.The NB679AGD-Z provides a fixed 5V 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 a QFN-12 2mm x 3mm package.
