XR75100ELTR-F

Overview

The XR75100ELTR-F is a synchronous buck controller from MaxLinear, designed for high-current applications up to 20A. It operates with an input voltage range of 5.5V to 40V and provides an adjustable output from 0.6V to 30V. The device supports switching frequencies between 100kHz and 800kHz. Key electrical parameters include a quiescent current of 700uA, rise time of 35ns, and fall time of 30ns. It features a non-isolated topology and includes a shutdown function. The component is housed in a QFN-16 package (3x3mm) and operates within a temperature range of -40°C to +125°C.

Feature Summary

• Supports continuous output currents up to 20A for demanding power delivery requirements
• Utilizes constant-on-time control architecture for fast transient response
• Enables flexible design through wide input and adjustable output voltage ranges
• Integrates shutdown functionality for system power management

Applications

• Server and data center point-of-load regulation
• Industrial equipment power distribution
• Telecommunications infrastructure systems
• High-performance computing modules

Procurement Notes

Verify the specific suffix 'MTR' indicates tape-and-reel packaging configuration distinct from tray options. Confirm RoHS compliance status via official documentation before integration. Ensure the supplier provides valid traceability records. Cross-reference the manufacturer part number against current production lifecycle status to avoid obsolescence risks during procurement planning.

Selection Notes

Select this controller when designing systems requiring high current capacity with flexible voltage adjustment. The wide input range accommodates various bus voltages common in industrial and telecom sectors. Consider the thermal performance of the QFN-16 package relative to the 20A load requirement. Evaluate the switching frequency range to optimize external component size versus efficiency trade-offs for the specific application constraints.
