Overview
The ADP3169JRU-REEL is a VRM9.0 compliant 2/3-phase synchronous buck controller designed for Intel Pentium IV processors. It features a 5-bit programmable voltage output range of 1.1V to 1.85V, supporting input voltages of 5V and 12V. The device utilizes a 20-TSSOP surface-mount package. As a specialized power management IC, it regulates CPU core voltage with high precision, ensuring stable operation for high-performance computing applications requiring specific voltage profiles defined by the VRM9.0 standard.
Feature Summary
- Complies with VRM9.0 specifications for Intel Pentium IV platforms
- Supports 2-phase or 3-phase synchronous buck conversion topologies
- Features 5-bit programmable output voltage control for precise regulation
Applications
- Intel Pentium IV processor voltage regulation modules
- High-performance desktop computer motherboards
- Server and workstation power supply designs
Procurement Notes
Verify component authenticity through authorized distributors due to discontinued status. Confirm package integrity and pin alignment against the 20-TSSOP specification. Review datasheet revisions for any design-in updates. Ensure compatibility with existing motherboard BIOS voltage tables. Validate thermal performance under maximum load conditions before final integration.
Selection Notes
Select this controller when designing for legacy Intel Pentium IV architectures requiring VRM9.0 compliance. Compare phase count requirements against current draw specifications. Evaluate PCB layout constraints for the 20-TSSOP footprint. Consider availability of compatible gate drivers and inductors. Assess system-level efficiency targets against alternative multi-phase controllers.
Part Context
This component belongs to Analog Devices' VRM controller family targeting early 2000s high-performance microprocessors. It sits alongside similar models like the ADP3163 and ADP3180, which offer varying phase counts and feature sets. The ADP3169 specifically addresses the power delivery needs of the Pentium IV platform, bridging the gap between single-phase simplicity and complex multi-phase solutions.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult Analog Devices technical support for direct replacements or evaluate newer VRM standards if migrating from legacy platforms.
