MAX20733

Integrated, Step-Down Switching Regulator

General Description

Beneﬁts and Features

The MAX20733 is a fully integrated, highly efficient

switching regulator for applications operating from 4.5V to

16V and requiring up to 35A maximum load. This single-

chip regulator provides extremely compact, high-efficien-

cy power-delivery solutions with high-precision output

voltages and excellent transient response for networking,

datacom, and telecom equipment.

●

High Power Density and Low Component Count

• Overall Solution Size: 509mm²Including Inductor

and Output Capacitors

• 90.8% Peak Efﬁciency: V

= 12V and

DDH

OUT

= 1V

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

Load Step Transients

The IC offers a broad range of programmable features

through capacitors and resistors connected to dedicated

programming pins. 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.

●

Optimized Component Performance and Efﬁciency

with Reduced Design-In Time

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 MAX20733 includes protection capabilities. 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 out-

put voltage is within range and the system is regulating.
