XRP7708ILB-F

Overview

The XRP7708ILB-F is a specialized power management IC from MaxLinear featuring five distinct voltage regulator outputs. It integrates four synchronous buck converters and one low-dropout (LDO) linear regulator within a single package. The device supports an input voltage range up to 20V and operates with switching frequencies reaching 1.5MHz, which facilitates the use of smaller passive components. This high level of integration allows for significant reduction in overall circuit board area while maintaining efficient power delivery for complex system requirements.

Feature Summary

• Integrates four synchronous buck converters and one LDO output
• Supports input voltages up to 20V
• High switching frequency reduces external component size

Applications

• Complex embedded systems requiring multiple regulated rails
• Industrial control units with mixed analog and digital power needs
• Communication infrastructure equipment

Procurement Notes

Verify component authenticity through authorized channels as this part is obsolete. Check for valid RoHS compliance documentation if required by your manufacturing standards. Ensure that any replacement strategy accounts for the discontinuation status and potential supply chain limitations associated with end-of-life products.

Selection Notes

Select this component when a compact solution for multiple power rails is needed. The combination of buck and LDO outputs suits designs requiring both high efficiency and low noise. Consider the 20V input tolerance and 1.5MHz operation when designing thermal management and PCB layout constraints.

Part Context

This part belongs to the MaxLinear PowerXR series, designed for highly integrated power management applications. It serves as a comprehensive solution for systems needing multiple regulated voltages from a single source, reducing bill of materials complexity compared to discrete regulator implementations.
