三路输出降压开关稳压器

A4491 可为打印机、办公自动化、工业及便携式设备供电，通过单个封装即可提供三路大电流、高性能、开关稳压器输出，节省空间、成本和减少元件数量。\n\n高频开关支持使用低成本电感器及小型陶瓷输出电容器。稳压器的开启周期相互交错，以最大化降低对输入电容器产生的应力，并减少 EMI。独立的“启用”引脚可简化加电排序和关机功能，用户可配置延迟的通电复位 (POR) 电路可在稳压器符合规格时发出指示。此外，当输入电压降至规格以下时，通电复位标志也会显示，以向系统控制器预先发出警告，而开关则继续工作至关断状态。\n\n内部诊断提供全面的过载、输入欠压及过温保护。\n\n三路输出的总输出电流能力为 ~4. • 三个降压转换器整合在一个封装中\n• 550 kHz 固定频率\n• 独立控制各个转换器的排序和关机控制\n• 内部补偿，以最大限度减少元件和简化设计\n• 4 ×4 mm QFN 封装, 小型 PCB;

Designed to provide the power supply requirements of printers, office automation, industrial, and portable equipment, the A4491 provides three high current,
