NCP5314FTR2

Overview

The NCP5314FTR2 is a switching controller designed for multi-phase buck CPU voltage regulation. It supports two, three, or four-phase configurations to meet varying processor power demands. The device operates with a maximum switching frequency of 1200 kHz. It is housed in a lead-free LQFP-32 package (PQFP32) measuring 7x7 mm. This controller is engineered for high-efficiency power delivery in computing applications requiring stable and responsive voltage conversion.

Feature Summary

• Supports flexible two, three, or four-phase buck converter topologies
• Capable of operating at switching frequencies up to 1200 kHz
• Integrated into a compact 32-pin LQFP package

Applications

• CPU voltage regulation modules
• Multi-phase DC-DC step-down converters
• High-performance computing power supplies

Procurement Notes

Verify the specific ordering suffix against official onsemi documentation to confirm package type and tape-and-reel specifications. Ensure the component matches the required LQFP-32 form factor and lead-free compliance standards before integration into the design.

Selection Notes

Select this controller when designing power stages for processors requiring dynamic phase shedding or fixed multi-phase operation. Consider the 1200 kHz maximum frequency for balancing efficiency and component size. Verify compatibility with the target CPU VID interface requirements.

Part Context

This component belongs to the family of synchronous buck controllers from onsemi. It is distinct from single-phase regulators and linear LDOs, serving specifically as a PWM controller for driving external MOSFETs in high-current CPU VRM designs.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Generic equivalents may not support the specific multi-phase control logic or frequency range.
