NB669 Overview
The NB669 is a fully integrated high frequency synchronous rectified step-down switch mode converter with 5V fixed output voltage. It offers very pact solution to achieve 6A continuous output current and 9A peak output current over a wide input supply range with excellent load and line regulation. The NB669 operates at high efficiency over a wide output current load range.
