NCP5318FTR2G

Overview

The NCP5318FTR2G is a multiphase synchronous buck controller utilizing Enhanced V2 topology. It supports 2, 3, or 4 output phases for CPU voltage regulation. The device operates with an input voltage range of 4.5V to 18V and delivers up to 40A total output current. It features a 32-LQFP (7x7) package and functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Implements Enhanced V2 control topology for fast transient response
• Configurable for two, three, or four phase operation
• Integrated gate drivers for synchronous buck applications

Applications

• CPU core voltage regulation
• Server and workstation power supplies
• Graphics processing unit (GPU) power delivery

Procurement Notes

Verify the specific suffix 'FTR2G' confirms the tape and reel packaging quantity of 2000 units. Ensure the component meets RoHS compliance standards required for your assembly process. Confirm the 32-LQFP footprint matches your PCB design guidelines before finalizing procurement orders.

Selection Notes

Select this controller when designing multi-phase power stages requiring high current capability up to 40A. It is suitable for applications needing rapid load transient response. Consider the 32-LQFP package size for board space constraints. Verify input voltage compatibility with the 4.5V to 18V operating range.

Part Context

Part of the NCP5318 series from onsemi, designed for high-performance digital power management. This family targets demanding computing loads where efficiency and dynamic response are critical. The FTR2G variant specifies the surface-mount reel packaging format for automated assembly lines.

Replacement Considerations

Check for pin-compatible alternatives within the same NCP5318 series. Verify that any substitute maintains the Enhanced V2 topology and 40A current rating. Ensure the replacement part supports the same 32-LQFP package dimensions.
