MAX20734

Integrated, Step-Down Switching

Regulator with PMBus

General Description

Beneﬁts and Features

● High Power Density and Low Component Count

The MAX20734 is a fully integrated, highly efficient switch-

ing regulator with PMBus™ for applications operating from

4.5V to 16V and requiring up to 40A (max) 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

• 90.7% Peak Efﬁciency with V

= 12V and V

DDH

= 1V

• 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 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 the 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.
