NCP5201MNR2

Overview

The NCP5201MNR2 is a dual output DDR power controller designed for high-current DDR memory systems. It integrates two PWM controllers in an 18-DFN (5x6) package with exposed pad. The device operates from a supply voltage range of 9.2V to 12V. It provides independent control for VDDQ and VTT rails, featuring soft-start capabilities and protection functions. This component serves as a complete power solution for synchronous DDR applications.

Feature Summary

• Dual output architecture supporting independent VDDQ and VTT regulation
• Integrated PWM controllers optimized for high-current DDR memory loads
• Compact 18-pin DFN package with thermal exposed pad for efficient heat dissipation

Applications

• DDR2 memory subsystems requiring dual rail power management
• DDR3 memory interfaces needing synchronized VDDQ and VTT supplies
• High-performance computing platforms with dense memory configurations

Procurement Notes

Verify the exact suffix MNR2 corresponds to the tape and reel packaging configuration. Confirm the manufacturer is onsemi or its authorized successor entity. Ensure the part number matches the specific 18-DFN footprint and pinout requirements of your design. Cross-reference with official datasheets to validate electrical specifications before integration.

Selection Notes

Select this component when designing DDR memory power stages requiring integrated dual-channel control. It is suitable for applications needing precise VTT termination voltage tracking relative to VDDQ. Consider the thermal performance of the exposed pad layout for high-current operation. Ensure input voltage compatibility within the specified 9.2V to 12V range for proper controller functionality.

Part Context

This part belongs to onsemi's specialized DDR power management portfolio. It complements linear regulators like the NCP51199 by providing the switching control stage for main memory voltages. The series addresses the complexity of powering modern synchronous DRAM modules with minimal external component count.

Replacement Considerations

Check for direct cross-reference part numbers from onsemi or other manufacturers offering identical dual-output DDR controller functionality. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution.
