XR75100EL-F

Overview

The XR75100EL-F is a synchronous buck controller from MaxLinear, designed for point-of-load supplies up to 20A. It features a wide input voltage range of 5.5V to 40V and an adjustable output voltage from 0.6V to 30V. The device operates at switching frequencies between 100kHz and 800kHz. It utilizes a non-isolated topology with a single output in a QFN-16 (3x3) package. Operating temperatures span from -40°C to +125°C, with a quiescent current of 700µA.

Feature Summary

Constant on-time control architecture for rapid transient response
Wide input voltage compatibility with standard DC/AC rails
Integrated shutdown functionality for power management

Applications

Point-of-load power supplies
12V, 18V, and 24V DC distribution systems
Industrial automation equipment

Procurement Notes

Verify the specific suffix 'EL' against official documentation to confirm tray packaging requirements. Ensure the component matches the required thermal performance for the intended operating environment. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status through the latest datasheet revision before finalizing procurement specifications.

Selection Notes

Select this controller when designing high-current synchronous buck converters requiring flexible input voltages. The constant on-time topology supports fast transient recovery. Evaluate the QFN-16 package constraints for PCB layout. Consider the 700µA quiescent current for efficiency calculations. Verify that the 20A output capability aligns with the load requirements and thermal dissipation capabilities of the system design.

Part Context

This component belongs to the XR75100 series of power management ICs manufactured by MaxLinear. It is categorized under switching controllers within the broader PMIC family. The device is specifically engineered for non-isolated step-down applications. It complements other MaxLinear solutions for industrial and commercial power distribution networks.
