NCP81105HMNTXG

Overview

The NCP81105HMNTXG is a single-output voltage regulator controller IC designed for Intel VR12.5 and VR12.6 specifications. It operates within an input voltage range of 4.75V to 5.25V and provides precise output regulation between 0.5V and 2.3V. The device is housed in a compact 36-QFN (5x5) package with an exposed pad, suitable for surface mount applications.

Feature Summary

• Compliant with Intel VR12.5 and VR12.6 specifications
• Single-output voltage regulation capability
• Integrated PWM switching control

Applications

• Intel platform power management systems
• Server and workstation voltage regulation
• Industrial computing power supplies

Procurement Notes

Verify the specific suffix 'H' against the manufacturer's current datasheet to confirm pinout and thermal characteristics. Confirm RoHS compliance status as regulatory requirements may vary by production batch. Ensure the 36-QFN package dimensions match the target PCB footprint before finalizing procurement decisions.

Selection Notes

Select this component when designing for Intel VR12.5 or VR12.6 architectures requiring a single regulated output. The 4.75V to 5.25V input range aligns with standard system rails. Consider the 36-QFN package size for space-constrained designs requiring exposed pad thermal dissipation.

Part Context

This part belongs to onsemi's portfolio of professional power management integrated circuits (PMIC). It functions as a dedicated switching controller rather than an integrated power stage, requiring external MOSFETs for high-current delivery. The series targets high-performance computing environments.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing design files before considering alternative components from other manufacturers.
