XRP7725ILB-F

Overview

The XRP7725ILB-F is a digital power management IC from MaxLinear, designed as a quad-channel programmable power management system. It integrates four step-down (buck) converters and two linear regulators (LDOs). The device operates with an input voltage range of 4.75 V to 25 V and provides adjustable output voltages from 600 mV to 5.5 V. It supports switching frequencies between 105 kHz and 1.23 MHz and delivers up to 130 mA output current per channel. The component utilizes an I2C interface for configuration and monitoring, housed in a TQFN-44 package.

Feature Summary

• Integrates multiple power stages including buck converters and LDOs within a single compact package
• Features digital programmability via I2C interface for flexible system configuration
• Supports wide input voltage ranges suitable for various industrial and commercial applications

Applications

• Industrial control systems requiring multi-rail power distribution
• Commercial infrastructure equipment needing programmable voltage regulation
• Embedded systems utilizing digital power management architectures

Procurement Notes

Verify the specific suffix and package variant against your design requirements before ordering. Confirm availability status as supply conditions may vary by region. Ensure compatibility with existing I2C bus configurations and thermal management solutions. Review the latest datasheet for any updates regarding operating conditions or pin assignments.

Selection Notes

Select this component when a high degree of flexibility in voltage regulation is required without using multiple discrete controllers. Consider the TQFN-44 footprint for space-constrained designs. Evaluate the thermal performance under maximum load conditions given the integrated nature of the power stages. Verify that the I2C address and communication speed meet system controller capabilities.

Part Context

This part belongs to the XRP7725 series of digital power management ICs. It represents a consolidated solution for managing multiple power rails in complex electronic systems. The series is characterized by its programmability and integration of both switching and linear regulation technologies.

Replacement Considerations

Check for alternative packages such as TR variants or different suffixes if lead-free compliance or specific tape-and-reel packaging is required. Consult manufacturer documentation for direct pin-to-pin replacements or functional equivalents within the same product family.
