XRP7713ILB-F

Overview

The XRP7713ILB-F is a PowerXR series PMIC featuring three buck regulators and one LDO. It operates with an input voltage range of 4.75V to 25V. Output voltages are adjustable from 0.9V to 5.1V for the buck channels. The switching frequency ranges from 300kHz to 1.5MHz. It includes a sequencer and functions within a temperature range of -40°C to 125°C. The device is housed in a 32-TQFN (5x5) package.

Feature Summary

• Integrates three synchronous buck converters and one low-dropout regulator for multi-rail power distribution.
• Features digital control via I2C interface for programmable output settings and sequencing.
• Includes internal sequencer to manage power-up and power-down timing of multiple rails.

Applications

• Powering broadband access equipment
• Digital subscriber line (DSL) systems
• MoCA network infrastructure

Procurement Notes

Verify component authenticity through authorized MaxLinear distributors or certified partners. Confirm the specific suffix matches the required package and tape/reel specifications. Check for recent Product Change Notices or End-of-Life notifications, as discontinuance notices have been recorded for this series. Ensure compliance with RoHS directives and humidity sensitivity levels before procurement.

Selection Notes

Select this component when designing systems requiring integrated digital control over multiple power rails. It is suitable for applications needing precise voltage regulation across varying load conditions. Consider the thermal performance of the TQFN package relative to the board layout. Verify that the I2C interface compatibility aligns with the system controller. Evaluate the switching frequency requirements against electromagnetic interference constraints.
