NCP5399FTR2G

Overview

The NCP5399FTR2G is a switching controller manufactured by onsemi, classified under PMIC - Power Management ICs. It functions as a 1/2 phase controller designed for Intel processor power applications. The device is supplied in a 32-LQFP package and is identified by the Mouser part number 863-NCP5399FTR2G. This specific component variant is currently listed as obsolete or discontinued in public distributor records.

Feature Summary

• Integrated control logic for single-phase or half-phase voltage regulation architectures
• Optimized interface compatibility with Intel processor core power requirements

Applications

• Intel processor core voltage regulation modules
• Single-phase DC-DC converter systems
• Half-phase power delivery circuits

Procurement Notes

Verify current availability status through authorized distributors, as public records indicate this part number may be discontinued. Confirm that the 32-LQFP package and Intel-compatible specifications align with existing design requirements before finalizing procurement plans. Check for valid obsolescence notifications or end-of-life notices from onsemi to ensure long-term supply chain stability.

Selection Notes

Select this component only if the design specifically requires an Intel-compatible 1/2 phase controller in a 32-LQFP package. Evaluate alternative active parts within the NCP5399 family or newer generations if continuous production is required. Ensure the application supports the legacy status of this specific suffix variant.

Part Context

This part belongs to the NCP5399 series of switching controllers. It shares functional similarities with other variants like the NCP5399MNR2G, which utilizes a 40-QFN package. Both are designed for similar Intel processor power management tasks but differ in physical footprint and pin configuration.

Replacement Considerations

Public data indicates the NCP5399MNR2G as a related variant within the same product family. Verify pin-to-pin compatibility and package differences (LQFP vs QFN) when considering substitutes.
