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.
