NCP81111MNI7TXG

Overview

The NCP81111MNI7TXG is a 3-phase VR12.5/VR12.6 controller IC manufactured by onsemi. It operates within an input voltage range of 5V and supports programmable output voltages. The device functions across a temperature range of -10°C to 100°C (TA). It is housed in a 32-VFQFN package with exposed pad, measuring 5x5 mm. This component is designed for high-performance power management applications requiring compliance with Intel VR12.5 and VR12.6 specifications.

Feature Summary

• Complies with Intel VR12.5 and VR12.6 regulator standards
• Supports 3-phase control architecture
• Features programmable output voltage capability

Applications

• Intel VR12.5 compliant systems
• Intel VR12.6 compliant systems
• Multiphase voltage regulation circuits

Procurement Notes

Verify the specific suffix '7' against official datasheets to confirm pinout and configuration compatibility. Check current availability status as distributors may list discontinued or limited stock items. Ensure the 32-QFN package matches your PCB footprint requirements. Confirm RoHS3 compliance if required by your manufacturing standards. Validate operating temperature range suitability for your specific environment.

Selection Notes

Select this component when designing systems requiring strict adherence to Intel VR12.5 or VR12.6 protocols. The 3-phase topology suits moderate current delivery needs compared to higher phase counts. Consider the 32-QFN package size for space-constrained layouts. Evaluate thermal performance within the specified -10°C to 100°C range. Compare against other NCP81111 variants if different packaging or suffix configurations are needed.

Part Context

This part belongs to the NCP81111 series from onsemi, specialized for CPU core voltage regulation. It integrates control logic for multiphase buck converters. The series targets desktop and server platforms requiring precise voltage tracking. Other variants in the family may differ in package type or operational suffixes while maintaining core controller functionality.

Replacement Considerations

NCP81111MNI5TXG and NCP81111MNDFTXG are related parts within the same series. Verify functional equivalence and pin compatibility before substitution. Note that some variants may be discontinued or have limited availability.
