NB671数据手册集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF

描述 Description

The NB671 is a fully integrated high frequency synchronous rectified step-down switch mode converter. It offers very compact solutions to achieve 6A continuous output current and 9A peak current over a wide input supply range with excellent load and line regulation. The NB671 operates at high efficiency over a wide output current load range. Constant-On-Time (COT) control mode provides fast transient response and eases loop stabilization. Under voltage lockout is internally set as 4.6V, An open drain power good signal indicates the output is within its nominal voltage range. Full protection features include OCP, OVP, and thermal shut down. The converter requires minimum number of external components and is available in QFN16 (3mmx3mm) package.
