NCP81109DMNTXG

Overview

The NCP81109DMNTXG is a single-phase synchronous buck regulator controller manufactured by onsemi, designed for high-performance voltage regulation in computing applications. It operates with an adjustable switching frequency ranging from 500 kHz to 1.2 MHz and supports output voltages from 0 V to 2.3 V. The device delivers up to 14 A of output current and functions within an ambient temperature range of -10°C to +100°C. Packaged in a 48-QFN (6x6 mm) surface-mount housing, it integrates control logic for efficient power management.

Feature Summary

Integrates synchronous buck regulation capabilities with internal MOSFETs for compact design
Supports programmable switching frequencies between 500 kHz and 1.2 MHz
Features shutdown functionality for power management efficiency

Applications

Single-phase voltage regulation for AMD Kintex US+ FPGA designs
Power delivery systems for AMD Virtex US+ FPGA architectures
General-purpose DC-DC conversion in computer application boards

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS3 compliance and REACH declaration requirements prior to integration. Check moisture sensitivity level (MSL 3) handling guidelines during storage and assembly. Validate package dimensions against PCB footprint specifications to ensure mechanical compatibility.

Selection Notes

Select this controller for applications requiring a single-phase solution with integrated power stages. Consider the 48-QFN package size for space-constrained layouts. Evaluate thermal performance requirements given the 14 A current capability and operating temperature range. Ensure input voltage ranges align with system power rails before implementation.

Part Context

Part of the NCP81109D series, this component serves as a specialized power management IC for high-density computing environments. It complements other onsemi PMIC solutions by offering a simplified single-phase architecture compared to multi-phase controllers. The device targets modern FPGA and processor power delivery needs where efficiency and board real estate are critical factors.
