5-24V宽Vin，6A，3.3V固定Vout，恒定导通时间（COT）控制模式同步降压变换器，带LDO调节器

NB670 是一款具有3.3V固定输出电压的全集成高频同步整流降压开关变换器。它提供了非常紧凑的解决方案，在宽输入范围内可实现6A连续输出电流和 9A 峰值输出电流，具有出色的负载和线性调整率。NB670在宽输出电流负载范围内可高效工作。其恒定导通时间控制模式（COT）提供了快速瞬态响应，并使环路更易稳定。NB670内部默认设置欠压锁定阈值为4.65 V，并通过一个开漏PG信号来指示输出是否在标称电压范围之内。NB670 提供了3.3V低压差（LDO）调节器，可为外围设备供电，如笔记本电脑的键盘控制器。另外还提供 300kHz CLK；其输出可驱动外部电荷泵，在不降低主变换器效率的前提下，为负 • 宽工作输入电压范围：5V 至 24V\n• 固定输出电压：3.3V\n• 带开关的内置 3.3V,100mA LDO\n• 连续输出电流：6A\n• 峰值输出电流：9A\n• 用于外部电荷泵的 300 kHz CLK\n• 内部低导通电阻功率 MOSFETs\n• 专有开关损耗降低技术\n• 内部软启动\n• 输出放电功能\n• 500kHZ开关频率\n• 过流保护（OCP）、过压保护（OVP）、欠压保护（UVP）和过温关断保护;
