NCP81109GMNTXG

Overview

The NCP81109GMNTXG is a single-phase voltage regulator controller manufactured by onsemi, designed for high-performance computing applications. It utilizes a buck topology to regulate DC-DC conversion with one output channel. The device is housed in a 48-QFN (6x6 mm) surface-mount package suitable for automated assembly. It supports switching frequencies up to 1.2 MHz and operates within an input voltage range of 5 V to 20 V. The controller features current and voltage mode control capabilities, ensuring stable regulation under varying load conditions.

Feature Summary

Single-phase buck topology for efficient DC-DC conversion
Supports both current mode and voltage mode control strategies
Integrated enable and power good signaling functions
Designed for high-frequency operation up to 1.2 MHz

Applications

Processor core voltage regulation
Graphics processing unit (GPU) power delivery
Field-programmable gate array (FPGA) power systems
High-performance server and workstation mainboards

Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Availability is restricted, and distributors may not stock new units. Verify the specific EOL date and any Product Change Notices (PCN) before procurement. Sourcing should focus on authorized channels to ensure authenticity, though genuine stock is likely limited or exhausted.

Selection Notes

Select this controller for single-phase applications requiring precise voltage regulation for modern processors. Ensure the design accommodates the 48-QFN package thermal requirements. Verify compatibility with the target processor's VID (Voltage ID) interface. Consider the discontinuation status when planning long-term production cycles, as alternative sourcing may be difficult.

Part Context

The NCP81109 series belongs to onsemi's portfolio of professional power management ICs tailored for CPU and GPU power delivery. These controllers are engineered to meet stringent transient response and efficiency standards required by advanced digital logic families. The GMNTXG suffix denotes the specific tape-and-reel packaging configuration for the QFN-48 variant.
