ADP3166JRU-REEL

Overview

The ADP3166JRU-REEL is a synchronous buck switching regulator controller manufactured by onsemi. It is designed for high-efficiency DC-to-DC conversion, typically stepping down main supply voltages such as 5 V or 12 V to the core supply voltages required by high-performance processors like Pentium 4 and Athlon. The device supports dual-output configurations and is optimized for VRM designs.

Feature Summary

• Synchronous buck topology for high efficiency
• Dual output capability for processor power
• Optimized for converting 5 V or 12 V inputs

Applications

• Intel CPU supply circuits
• VRM 9.0 FMB design
• High-performance processor core voltage generation

Procurement Notes

Verify the specific suffix 'JRU' against official datasheets to confirm package type and temperature range. Ensure the reel quantity matches project requirements. Confirm RoHS compliance status through manufacturer documentation before procurement.

Selection Notes

Select this component for applications requiring efficient step-down conversion from standard 5 V or 12 V rails to lower processor core voltages. Consider its dual-output nature if multiple voltage domains are needed. Verify thermal management requirements for the chosen package.

Part Context

Part of the ADP316x family of synchronous buck controllers. Related models include ADP3167 and ADP3160, which share similar functionalities but may differ in current handling capabilities or specific feature sets tailored for different processor generations.

Replacement Considerations

Check ADP3167 and ADP3160 for potential functional equivalents. Verify pin compatibility and electrical specifications with official substitution guides.
