XRP9710EY-F

Overview

The XRP9710EY-F is a triple-output power management IC featuring two synchronous buck converters and one linear regulator. It operates within an input voltage range of 4.75V to 22V. The first two outputs provide adjustable voltages from 0.6V to 5.5V with up to 6A current capacity each. The third output delivers a fixed 5V at 135mA. Switching frequencies for the buck regulators are programmable between 126kHz and 1.23MHz. The device is housed in a 45-LGA (12x12) package and supports operation temperatures from -40°C to 125°C.

Feature Summary

• Integrates dual high-current synchronous buck converters alongside a dedicated low-power LDO for comprehensive multi-rail power sequencing.
• Features programmable switching frequency allowing optimization for efficiency or component size across a wide operational range.
• Includes built-in sequencing logic to manage power-up and power-down transitions for complex system requirements.

Applications

• Multi-voltage rail systems requiring synchronized power delivery
• Industrial control boards with mixed analog and digital loads
• Embedded communication modules needing compact PMIC solutions

Procurement Notes

Verify component authenticity through authorized channels as this part is listed as obsolete. Confirm package integrity and pin alignment against the 45-LGA specification before integration. Review the official datasheet for any specific handling or storage conditions required for legacy inventory.

Selection Notes

Select this component when a single solution is needed for multiple voltage rails including high-current digital cores and stable analog supplies. Evaluate thermal performance under maximum load conditions due to the dense 12x12mm package. Ensure the input voltage range aligns with the system's primary power source capabilities.

Part Context

This device belongs to the XRP9710 family of power management integrated circuits designed for space-constrained applications. It consolidates multiple regulation functions into a single footprint, reducing board area compared to discrete solutions. The family targets designs requiring precise voltage regulation and controlled startup sequences.

Replacement Considerations

Check for direct cross-references within the MaxLinear portfolio. Verify that alternative parts match the 45-LGA package dimensions and pinout configuration. Ensure replacement components support the same input voltage range and output current specifications.
