NCP5220AMNR2G

Overview

The NCP5220AMNR2G is a specialized power controller designed for MCH and DDR memory applications. It integrates dual PWM buck regulators and a linear regulator to provide VDDQ, VTT, and VREF voltages. The device operates with an input voltage range of 5V to 12V. It utilizes a 20-DFN (6x5 mm) package with exposed pad for surface mount installation. The component supports multiple output configurations to meet the specific power requirements of modern memory systems.

Feature Summary

• Integrates dual PWM buck converters and a linear regulator in a single solution
• Optimized for generating VDDQ, VTT, and VREF voltages for DDR memory
• Supports flexible configuration for various memory interface standards

Applications

• MCH power supply design
• DDR memory module power regulation
• System board voltage generation for chipset interfaces

Procurement Notes

Verify RoHS compliance status as datasheets indicate potential non-compliance for this specific suffix variant. Confirm package dimensions match the 20-DFN (6x5 mm) specification. Check for obsolescence notices or PCN documentation regarding manufacturing changes. Ensure supplier provides valid traceability for automotive or industrial grade requirements if applicable.

Selection Notes

Select this component when a combined solution for dual buck and linear regulation is required for memory interfaces. Consider the 5V to 12V input range compatibility with system rails. Evaluate thermal performance due to the integrated linear regulator section. Verify that the 20-DFN footprint fits the PCB layout constraints compared to alternative packages.

Part Context

Part of the NCP5220 family of special purpose voltage regulators. Designed specifically for high-performance computing and memory subsystems. Replaces discrete regulator solutions to reduce board space and component count. Shares functional similarities with other DDR power controllers but offers integrated linear regulation capabilities.

Replacement Considerations

Check for NCP5220 variants with different suffixes for updated RoHS compliance. Verify pin-to-pin compatibility with existing designs before substitution. Consult official replacement lists for end-of-life notifications.
