ADP3203JRU-0.85-R7

Special Purpose Regulators Overview

The ADP3203JRU-0.85-R7 is a two-phase IMVP core controller manufactured by Analog Devices Inc., designed for mobile CPU power applications. It operates as a current-mode switching controller in a PDSO28 package. The device supports IMVP-II and IMVP-III standards, providing regulated voltage output with a nominal setting of 0.85V. It integrates essential control logic for multiphase DC-DC conversion, ensuring stable performance for processor core supplies.

Special Purpose Regulators Feature Summary

• Implements two-phase current-mode control architecture for efficient power delivery
• Complies with Intel IMVP-II and IMVP-III specifications for mobile processors
• Integrates dedicated control logic for synchronous buck converter operation

Special Purpose Regulators Applications

• Mobile CPU core voltage regulation
• IMVP-II compliant power supply designs
• IMVP-III compliant power supply designs

Special Purpose Regulators Procurement Notes

Verify the specific suffix R7 indicates tape and reel packaging configuration when sourcing. Confirm the 0.85 designation matches the required output voltage reference for the target application. Ensure compatibility with existing PCB footprints for the PDSO28 package. Cross-reference manufacturer documentation to validate RoHS compliance status for the specific production batch.

Special Purpose Regulators Selection Notes

Select this component for designs requiring strict adherence to Intel IMVP-II or IMVP-III protocols. It is suitable for applications needing a fixed two-phase topology rather than programmable phase counts. Consider thermal management requirements associated with the PDSO28 package. Evaluate system efficiency needs against the capabilities of other IMVP controllers if variable phase counts are necessary.

Special Purpose Regulators Part Context

This part belongs to the ADP3203 family of power management ICs from Analog Devices. It serves as a specialized controller within the company's portfolio for mobile computing platforms. The series includes variants supporting different voltage references and packaging options. It complements other components in the IMVP ecosystem designed for low-power processor architectures.

Special Purpose Regulators Replacement Considerations

Direct substitutes include other ADP3203 variants with different voltage suffixes or packaging codes. Verify pin-to-pin compatibility before substitution. Check for updated revisions in the IMVP controller lineup that may offer enhanced features while maintaining electrical equivalence.
