NCP81250MNTXG

Overview

The NCP81250MNTXG is a single-phase synchronous buck switching voltage regulator from onsemi, designed for industrial temperature applications. It operates with an input voltage range of 5 V to 20 V and delivers up to 14 A output current. The device supports adjustable output voltages from 0 V to 2.3 V and features a programmable switching frequency between 500 kHz and 1.2 MHz. It utilizes a QFN-48 package and functions within a temperature range of -40 °C to +125 °C.

Feature Summary

• Single-phase synchronous buck topology for efficient power conversion
• Integrated high-side and low-side gate drivers for external MOSFETs
• Programmable switching frequency to optimize efficiency and component size
• Wide input voltage range suitable for various system rails

Applications

• Industrial control systems requiring robust power regulation
• Point-of-load (POL) conversion in server infrastructure
• Communication equipment power distribution networks
• General-purpose DC-DC conversion for embedded systems

Procurement Notes

Verify the specific suffix 'MNTXG' against the manufacturer's official datasheet to confirm the tape and reel packaging configuration and lead time requirements. Ensure compatibility with your PCB footprint for the QFN-48 package. Cross-reference the latest RoHS compliance status and material declarations directly from onsemi documentation prior to finalizing procurement orders.

Selection Notes

Select this component when a single-phase solution is sufficient for loads up to 14 A. Consider the wide input voltage range if the supply rail varies significantly. Evaluate thermal performance requirements given the operating temperature range up to +125 °C. Compare against multi-phase controllers if higher current density or reduced ripple is required for the specific application design.

Part Context

This part belongs to the NCP812xx series of switching regulators from onsemi, which are widely used in computing and industrial applications. The series includes various configurations for single and multi-phase designs. The NCP81250 specifically targets single-phase needs, offering a balance between simplicity and performance for moderate current applications compared to higher-phase counterparts.

Replacement Considerations

Check for direct pin-compatible alternatives within the NCP812xx family, such as the NCP81251, if additional features like Intel VR12 compatibility are needed. Verify that any substitute maintains the same QFN-48 package dimensions and electrical specifications, particularly the 14 A current rating and 20 V maximum input voltage.
