NCP81111MNI6TXG

Overview

The NCP81111MNI6TXG is a 3-phase voltage regulator controller designed for Intel VR12.5 and VR12.6 applications. It features a single output with programmable voltage capabilities. The device operates within an input voltage range of 4.75V to 5.25V and supports a working temperature range from -10°C to 100°C (TA). It is housed in a 32-VFQFN package with exposed pad, measuring 5x5 mm. The component is RoHS3 compliant and classified under ECCN EAR99.

Feature Summary

Designed specifically for Intel VR12.5 and VR12.6 voltage regulator standards
Provides 3-phase control for synchronous buck converter topologies
Supports programmable output voltage regulation

Applications

Intel VR12.5 compliant CPU power supply designs
Intel VR12.6 compliant processor voltage regulation
Multi-phase synchronous buck controller implementations

Procurement Notes

Verify the specific suffix '6' against official onsemi documentation to confirm pinout and feature set alignment with other NCP81111 variants. Check current lifecycle status as some NCP81111 variants have reached end-of-life. Ensure compatibility with target motherboard or carrier board design requirements before procurement.

Selection Notes

Select this component when designing for Intel VR12.5 or VR12.6 specifications requiring a 3-phase solution. Consider the 32-QFN package constraints for PCB layout. Verify that the 5V input requirement matches the system's available rail. Compare against newer generations if future-proofing is required.

Part Context

The NCP81111 series consists of multi-phase controllers optimized for Intel processor power delivery. This specific model targets the VR12.5/VR12.6 standards, differing from earlier VR11 or later IMVP versions. It belongs to onsemi's professional PMIC portfolio for computing applications.

Replacement Considerations

Check for direct substitutes within the NCP81111 family such as NCP81111MNI0TXG or NCP81111MNI7TXG, noting potential differences in packaging or lifecycle status. Consult onsemi datasheets for functional equivalence.
