NCP81111MNI5TXG

Overview

The NCP81111MNI5TXG is a 3-phase VR12.5 controller manufactured by onsemi, designed for Intel VR12.5 and VR12.6 voltage regulator applications. It operates within a temperature range of -10°C to 100°C (TA) and accepts a 5V input voltage. The device features a programmable output with one output channel and is housed in a 32-VFQFN package with an exposed pad, specifically a 32-QFN(5x5) configuration. This component is classified as a switching voltage regulator under PMIC special purpose regulators.

Feature Summary

• Supports Intel VR12.5 and VR12.6 voltage regulator standards
• Configured as a 3-phase multiphase controller
• Features programmable output voltage capability

Applications

• Intel VR12.5 compliant voltage regulation systems
• Intel VR12.6 compliant voltage regulation systems
• Multiphase power supply designs for computing platforms

Procurement Notes

Verify current availability status as the NCP81111MNI5TXG has been identified as End-of-Life (EOL) with manufacturer discontinuation notifications. Confirm if alternative revisions such as the MNI7 variant are available for new designs. Ensure compliance with RoHS3 specifications and check for any specific process change notifications or temporary certification suspensions affecting production batches before finalizing procurement plans.

Selection Notes

Select this component for designs requiring strict adherence to Intel VR12.5/VR12.6 protocols. Consider the 32-QFN package constraints for thermal management and PCB layout. Evaluate the -10°C to 100°C operating temperature range against system environmental requirements. Verify that the 5V input specification aligns with the upstream power stage design.
