EVALUATION KIT AVAILABLE

MAX20751

Multiphase Master with PMBus Interface

and Internal Buck Converter

General Description

Beneﬁts and Features

● Increased Power Density with Fewer External

The MAX20751 PMBus™-compliant multiphase

master IC, with extensive status and parameter monitor-

ing, is capable of driving up to four smart-slave integrated

power devices.

Components Needed

• Scalable, Multiphase Solution

• Compatibility with Coupled Inductors Enables Fast

Transient Response and Reduced C

• Integrated Internal Switching Regulator to Power

Smart Slaves

OUT

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 commu-

nication equipment. Proprietary-coupled inductors,

recommended to reduce the effective inductor value with-

out excessive ripple current, results in improved transient

response and reduction in the number of output capaci-

tors required.

● Optimized Component Performance and Efficiency

with Reduced Design-In Time

• PMBus-Compliant Interface for Telemetry and

Power Management

• Field-Programmable Memory to Allow Storage of

Desired Conﬁguration Parameters

• Fault Logging

The device incorporates current reporting, tempera-

ture 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.

● Comprehensive System and IC Self-Protection

Features Promote Increased Power-Supply Reliability

• Overcurrent and Overtemperature

• Boost Voltage UVLO

• VX Short to Ground or V

Detection

DDH

• Phase-Current Steering for Thermal Balancing

The device features an integrated switching regulator

● 36-Pin (6mm x 6mm) QFN Package

that can optionally be used to supply the V

rail for the

master controller and smart-slave devices to reduce the

power-rail requirements and simplify the regulator design.

Applications

● Communication, Networking, Servers, and Storage
