NCP5210MNR2

Overview

The NCP5210MNR2 is a specialized power management integrated circuit designed for DDR memory voltage regulation. It functions as a 3-in-1 PWM controller, integrating dual buck converters and a linear regulator to provide three distinct output channels. This configuration ensures stable power delivery for DDR modules. The device operates within an input voltage range of 4.5V to 13.2V. It is housed in a compact 20-DFN (6x5) package, suitable for surface mount applications requiring high integration and efficient power management for memory subsystems.

Feature Summary

• Integrates dual PWM buck converters and one linear regulator into a single chip
• Provides three independent output channels optimized for DDR memory power requirements
• Designed specifically for stable voltage regulation in memory subsystems

Applications

• DDR memory voltage regulation
• Computer motherboard power systems
• Server memory power supplies

Procurement Notes

Verify the specific suffix 'MNR2' against official onsemi documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with your PCB footprint for the 20-DFN (6x5) package. Cross-reference the datasheet revision date to confirm technical parameters match your design requirements before finalizing procurement.

Selection Notes

Select this component when designing DDR memory power stages requiring integrated control for multiple rails. It simplifies board layout by combining buck and linear regulation functions. Consider its input voltage range and thermal performance relative to your system's power density constraints. Verify that the 3-output architecture aligns with your specific memory module voltage profiles.

Part Context

This part belongs to onsemi's portfolio of specialized power management ICs (PMIC). It falls under the category of DDR voltage regulators, addressing the specific needs of dynamic random-access memory power delivery. The integration of multiple converter types allows for reduced component count compared to discrete solutions.

Replacement Considerations

Check for updated revisions such as NCP5210MNR2G if lead times or availability are critical. Verify pin-to-pin compatibility with existing designs if substituting. Consult official substitution guides for any functional differences in newer iterations.
