NCP3218GMNR2G

Overview

The NCP3218GMNR2G is a highly efficient, multi-phase synchronous buck switching regulator controller designed for mobile CPU applications. It supports Intel IMVP-6.5 voltage regulator specifications and features integrated drivers for simplified implementation. The device operates with an input voltage range of 3.3V to 22V and provides an adjustable output voltage from 0.013V to 1.5V. Packaged in a 48-QFN (6x6) format, it delivers up to 52A output current with a switching frequency of 1 MHz.

Feature Summary

• Supports Intel IMVP-6.5 voltage regulator interface standards
• Integrates high-side and low-side gate drivers for reduced component count
• Features 7-bit programmable control for precise voltage regulation

Applications

• Mobile CPU power supply designs
• Intel IMVP-6.5 compliant systems
• Multi-phase synchronous buck converter implementations

Procurement Notes

Verify the specific suffix 'GMNR2G' against the manufacturer's latest documentation to confirm package type and tape-and-reel quantity. Ensure compatibility with Intel IMVP-6.5 requirements for target applications. Check for any recent obsolescence notices or alternative recommendations from onsemi before finalizing procurement plans.

Selection Notes

Select this controller for applications requiring strict adherence to Intel IMVP-6.5 protocols. The integrated driver capability reduces external BOM size compared to discrete solutions. Consider the 48-QFN package constraints for thermal management and PCB layout space when designing the power stage.
