Overview
The NCP81111MNTXG is a 3-phase VR12.5 controller IC manufactured by onsemi, designed for high-performance voltage regulation in computing applications. It operates within an input voltage range of 5V and supports programmable output voltages. The device features a 32-QFN (5x5) package with exposed pad for efficient thermal management. Operating temperatures span from -10°C to 100°C ambient. It complies with Intel VR12.5 and VR12.6 specifications, ensuring compatibility with modern processor power delivery requirements.
Feature Summary
- Supports Intel VR12.5 and VR12.6 voltage regulator standards
- Provides three-phase control for multi-core processor power delivery
- Features programmable output voltage capability
- Integrated thermal protection and shutdown mechanisms
Applications
- Intel Core processor power supply designs
- Server and workstation motherboard voltage regulation modules
- High-performance desktop computer systems requiring VR12.5 compliance
Procurement Notes
Verify the exact suffix 'MNTXG' against official onsemi documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with target PCB footprint for the 32-VFQFN package. Check current availability status as distribution channels may list discontinued or obsolete variants under similar part numbers. Confirm RoHS3 compliance if required by specific regional regulations.
Selection Notes
Select this component when designing for Intel VR12.5 compliant platforms requiring three-phase power delivery. Compare against single-phase alternatives like NCP81109 if lower current demands exist. Consider the 32-QFN package constraints for layout density. Verify that the 5V input requirement aligns with system power rails. Evaluate thermal performance needs given the 100°C operating limit.
Part Context
This part belongs to the NCP81111 series of multiphase controllers from onsemi. It is distinct from the NCP81116 buck controller and the NCP81109 single-phase regulators. The series targets CPU core voltage regulation, differing from general-purpose DC-DC converters. It complements other VR12.5 compliant parts in the portfolio for complete system power solutions.
Replacement Considerations
NCP81111MNI7TXG is a verified alternative within the same family offering identical VR12.5 functionality. NCP81111MNI5TXG is another variant but may have different packaging or suffix specifications. Verify pinout and electrical parameters before substitution.
