说明

MAX20734为全集成、高效开关调节器,带有PMBus,适用于4.5V至16V工作电压和最大40A负载电流的应用。该单芯片调节器提供极其紧凑、高效的电源方案,具有高精度输出电压和优异的瞬态响应,适用于网络、数据通信和电信设备。

IC提供较宽范围的可编程特性,可通过PMBus或者连接到专用编程引脚的电容和电阻进行设置。利用该特性,可根据具体应用优化操作,减少元件数量和/或综合考虑调节器性能与系统成本。编程的简单性支持相同设计适用于多种应用。

IC包括保护和遥测特性。正和负逐周期过流保护和过热保护确保设计坚固耐用。输入电压超出指标范围时,输入欠压锁定功能关断器件,禁止操作。状态引脚提供输出信号,指示输出电压在范围之内以及系统正在进行调节。

PMBus是SMIF, Inc.的商标。
