XR71211EHTR-F

Overview

The XR71211EHTR-F is a synchronous buck DC-DC controller manufactured by MaxLinear. It operates with an input voltage range of 4.5V to 22V and provides an adjustable output voltage from 0.6V to 18V. The device supports up to 20A output current and features a programmable switching frequency between 200kHz and 1MHz. It utilizes a QFN-17 5x6mm package and functions within a temperature range of -40°C to +125°C.

Feature Summary

Integrates controller, drivers, bootstrap diode, and MOSFETs for point-of-load supplies
Utilizes Constant-On-Time (COT) control architecture
Supports high efficiency with wide input voltage range

Applications

Point-of-load power supplies
Industrial equipment power distribution
Telecommunications infrastructure

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm package integrity and pin alignment prior to assembly. Review latest Product Change Notifications for any metal mask or yield improvements that do not alter datasheet specifications. Ensure supply chain stability given potential availability constraints.

Selection Notes

Select this component for applications requiring integrated synchronous buck solutions with COT control. Consider the 20A current capability and wide input range when designing for industrial or telecom loads. Evaluate thermal performance in the QFN-17 package against system heat dissipation requirements.

Part Context

This part belongs to the XR761xx series of PowerBlox regulators. It combines all necessary components for a step-down converter into a single unit. The series is designed for high-density power applications where space and efficiency are critical constraints.
