XR75100ELMTR-F

Overview

The XR75100ELMTR-F is a synchronous buck switching controller from MaxLinear, designed for point-of-load power supplies up to 20A. It features a wide input voltage range of 5.5V to 40V and supports adjustable output voltages from 600mV to 30V. The device operates with a switching frequency between 100kHz and 800kHz. It utilizes a constant on-time (COT) control architecture and includes shutdown functionality. The component is housed in a 16-lead QFN package measuring 3mm x 3mm, rated for operation between -40°C and +125°C.

Feature Summary

Synchronous step-down topology optimized for high-current point-of-load applications
Constant on-time control architecture for fast transient response
Wide input voltage capability supporting standard 12V, 18V, and 24V rails
Integrated shutdown pin for system power management

Applications

Point-of-load DC/DC conversion for industrial equipment
Power distribution from 12V, 18V, or 24V AC/DC rails
High-current load regulation in telecommunications infrastructure

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verify end-of-life status and last-time-buy availability through authorized channels. Ensure replacement strategies are evaluated immediately due to discontinuation. Cross-reference datasheets for any final production lot specifications before procurement decisions.

Selection Notes

Select this controller for designs requiring up to 20A output current with a 40V maximum input. The 100kHz to 800kHz frequency range allows flexibility in passive component selection. Consider the 3x3mm QFN package constraints for thermal management and PCB layout. Validate compatibility with external MOSFETs for the target current rating.

Part Context

Part of the XR75100 series, which includes variants like XR75100EL-F. The 'MTR' suffix typically indicates tape-and-reel packaging, while 'EL' denotes the specific electrical grade and package type. This series focuses on synchronous buck control for medium-to-high current applications.
