NCP51200MNTXG

Overview

The NCP51200MNTXG is a specialized PMIC DDR termination regulator from onsemi, designed for high-speed memory interfaces. It features a 3 A sink/source output current capability and operates with an input voltage range of 2.375 V to 5.5 V. The device includes a buffered VTTREF reference and supports DDR1, DDR2, and DDR3 standards. Packaged in a DFN-10 surface-mount format, it functions within a temperature range of -40 °C to +125 °C and draws 700 uA input current. It holds AEC-Q100 qualification.

Feature Summary

• Provides bidirectional 3 A sink and source current for precise DDR termination control
• Integrates a buffered VTTREF reference for accurate voltage tracking
• Supports multiple DDR generations including DDR1, DDR2, and DDR3
• Qualified for automotive applications under AEC-Q100 standards

Applications

• DDR1 memory termination circuits
• DDR2 memory termination circuits
• DDR3 memory termination circuits
• AMD Artix US+ FPGA power systems
• AMD Virtex US+ FPGA power systems

Procurement Notes

Verify the specific suffix against official datasheets to confirm package and tape/reel specifications. Confirm AEC-Q100 compliance requirements match your target application environment. Ensure input voltage constraints between 2.375 V and 5.5 V align with your system design. Check thermal management needs for the DFN-10 package at maximum load conditions.

Selection Notes

Select this component when designing for DDR1, DDR2, or DDR3 memory buses requiring integrated termination regulation. The built-in buffered reference simplifies layout by reducing external component count. Consider the DFN-10 package for space-constrained designs. Verify that the 3 A current rating meets the peak transient demands of the connected memory modules.

Part Context

This part belongs to the NCP51200 series of professional power management ICs. It complements other regulators like the NCP51400 in complex power trees for high-performance processors. The series targets applications needing reliable, low-noise termination voltages for synchronous dynamic random-access memory interfaces.

Replacement Considerations

NCP51400MNTXG offers similar termination regulation but lacks the buffered VTTREF reference feature found in the NCP51200MNTXG.
