Analog Devices / Maxim Integrated MAX20751 PMBus 多相主集成电路
美信集成 MAX20751 PMBus™ 多相主控 IC 能够驱动多达四个智能集成的电源从设备。该器件采用美信智能从动 IC，是一款高密度和灵活的解决方案，可专门定制以适应通信设备中使用的一系列功率负载。
The device incorporates current reporting, temperature monitoring, fault detection, and PMBus support. The individual smart slaves detect overcurrent and overtemperature faults and faults communicated through the master IC. The highest junction temperature is reported both before and after smart-slave regulation.
The device features an integrated switching regulator that can optionally supply the VDD rail for the master controller and smart-slave devices to reduce the power-rail requirements and simplify the regulator design.
