NCP81210MNTXG

Overview

The NCP81210MNTXG is a switching voltage regulator controller designed for Intel IMVP8 applications. It operates as a single-phase step-down converter with a fixed output voltage of 5 V and a maximum output current capability of 97 mA. The device supports a switching frequency range from 150 kHz to 1.2 MHz and features a maximum duty cycle of 100%. It functions within an input voltage range of 4.5 V to 20 V, delivering up to 4.1 W of output power. The component is housed in a 40-QFN surface-mount package and is rated for operation between -40°C and +100°C.

Feature Summary

• Designed specifically for Intel IMVP8 single-phase regulator architectures
• Supports high-resolution buck control with adjustable switching frequencies
• Integrated shutdown functionality for power management flexibility

Applications

• Intel IMVP8 CPU voltage regulation
• Single-phase DC-DC conversion systems
• High-resolution power supply controllers

Procurement Notes

Verify the obsolete status of this component before integration into new designs. Confirm that existing inventory or last-time-buy options meet project requirements. Ensure compatibility with legacy Intel IMVP8 specifications if used in maintenance or replacement scenarios. Check for RoHS compliance documentation and material declarations prior to procurement.

Selection Notes

Select this controller only for systems requiring Intel IMVP8 compatibility. Consider the limited output current and single-phase topology constraints. Evaluate thermal performance within the specified temperature range. Verify that the 40-QFN package fits the PCB layout constraints. Assess availability due to end-of-life status.

Part Context

This part belongs to onsemi's portfolio of high-resolution buck controllers. It is distinct from multi-phase variants like the NCP81232 series. The NCP81210 focuses on single-channel precision control for specific processor voltage rails. It differs from general-purpose regulators by its strict adherence to Intel IMVP8 signaling and timing requirements.

Replacement Considerations

No direct public substitute part numbers are confirmed for this obsolete component. Designers should evaluate newer Intel platform controllers or multi-phase solutions if migrating to active parts.
