Analog Devices / Maxim Integrated MAX20751 PMBusマルチフェーズマスターIC
Maxim Integrated MAX20751 PMBus™マルチフェーズマスターICは、最大4つのスマートスレーブ統合パワーデバイスを駆動する能力があります。MaximのスマートスレーブICを活用して、このデバイスは高密度と柔軟性の高いソリューションを実現しており、通信機器に使用されるさまざまな電力負荷に対してカスタマイズできます。
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.
