NB670 24V, High Current Synchronous Buck Converter With LDO NOT RECOMMENDED FOR NEW DESIGNS DESCRIPTION The NB670 is a fully integrated high frequency synchronous rectified step-down switch mode converter with 3.3V fixed output voltage. It offers very compact 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 NB670 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 4.65 V. An open drain power good signal indicates the output is within its nominal voltage range. NB670 also provides a 3.
