MAX20743

Integrated, Step-Down Switching

Regulator with PMBus

General Description

Beneﬁts and Features

● High-Power Density and Low Component Count

The MAX20743 is a fully integrated, highly efficient

switching regulator with PMBus™ for applications

operating from 4.5V to 16V and requiring up to 35A

maximum load. This single-chip regulator provides

extremely compact, high-efficiency power delivery

solutions with high-precision output voltages and excellent

transient response for networking, datacom and telecom

equipment.

• Overall Solution Size 509mm Including Inductor

and Output Capacitors

• 90.8% Peak Efficiency with V

= 12V and

DDH

= 1V

OUT

• Fast Transient Response: Supports Up to 300A/μs

Load-Step Transients

● Optimized Component Performance and Efficiency

with Reduced Design-In Time

The IC offers a broad range of programmable features

through either the PMBus or through a capacitor and

resistor connected to a dedicated programming pin.

Using this feature, the operation can be optimized for a

specific application, reducing the component count and/

or setting appropriate trade-offs between the regulator’s

performance and system cost. Ease of programming

enables using the same design for multiple applications.

• PMBus-Compliant Interface for Telemetry and

Power Management

• Voltage, Current and Temperature Reporting

through Digital Bus

● Increased Power-Supply Reliability with System and

IC Self-Protection Features

• Differential Remote Sense with Open-Circuit

Detection

• Hiccup Overcurrent Protection

• Programmable Thermal Shutdown

The IC includes protection and telemetry features. Positive

and negative cycle-by-cycle overcurrent protection and

overtemperature protection ensure a rugged design. Input

undervoltage lockout shuts down the device to prevent

operation when the input voltage is out of specification.

A status pin provides an output signal to show that the

output voltage is within range and the system is regulating.
