NCP81270MNTXG

Overview

The NCP81270MNTXG is a single-phase switching voltage regulator from onsemi, designed for computer applications. It operates with a VCC supply range of 4.75V to 5.25V. The component utilizes current-mode control topology and is housed in a QFN-20 package (Case Outline 485EE). It is classified under PMIC - Power Management ICs and Switching Voltage Regulators. The device supports surface mount installation and is available in reel packaging with a standard quantity of 4000 units.

Feature Summary

Single-phase step-down voltage regulation architecture
Current-mode control strategy for stable operation
Integrated thermal pad design for heat dissipation

Applications

Computer system power distribution
CPU core voltage regulation
GPU power supply stages

Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and electrical characteristics, as variations exist within the NCP81270 family. Confirm RoHS compliance status and MSL rating prior to assembly planning. Ensure the ordering quantity aligns with the manufacturer's standard reel size requirements to avoid handling fees or partial reel constraints.

Selection Notes

Select this component when a dedicated single-phase controller is required for low-current CPU or GPU loads. Compare against multi-phase alternatives if higher current delivery is needed. Verify that the 4.75V to 5.25V VCC range matches the system's auxiliary power availability. Check compatibility with external MOSFET selection for the target load current.

Part Context

This part belongs to the NCP81270 series, which includes variants like NCP81270CMNTXG and NCP81270DMNTXG. These devices are positioned as cost-effective solutions for simple single-phase power rails in computing platforms. The series shares common control logic but may differ in package dimensions or specific electrical tolerances.
