产品概述

The MAX20751 PMBus™-compliant multiphase master IC, with extensive status and parameter monitoring, is capable of driving up to four smart-slave integrated power devices.

Utilizing Maxim’s smart-slave ICs, the device provides a high-density and flexible solution that can be tailored to a range of power loads used in communication equipment. Proprietary-coupled inductors, recommended to reduce the effective inductor value without excessive ripple current, results in improved transient response and reduction in the number of output capacitors required.

The device incorporates current reporting, temperature monitoring, fault detection, and PMBus support. Overcurrent and overtemperature faults are detected by the individual smart slaves 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 be used to supply the VDD rail for the master controller and smart-slave devices to reduce the power-rail requirements and simplify the regulator design.
