Special Purpose Regulators Procurement Notes

Verify the current product status before procurement planning. Official sources indicate this part may be discontinued or subject to temporary supply limitations. Confirm availability directly with the manufacturer or authorized distributors. Ensure the 16-SOIC package and specific suffix match design requirements. Do not assume stock availability without explicit verification from official channels.

Special Purpose Regulators Selection Notes

Select this component only for designs targeting Intel Pentium II or compatible legacy processor architectures. The 5-bit synchronous buck topology is specialized for these specific voltage regulation needs. Evaluate compatibility with existing board layouts requiring a 16-SOIC footprint. Consider that newer processor generations may require different control interfaces or higher performance regulators not provided by this legacy part.

Special Purpose Regulators Part Context

The CS5159 belongs to onsemi's portfolio of special purpose regulators and PMICs. It falls under the category of controllers designed for specific CPU voltage regulation tasks. This series includes related parts like the CS5151, which offers similar functionality for Pentium II/Pro applications but with asynchronous configurations. These components represent specialized solutions for early high-performance computing power management.

Special Purpose Regulators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The CS5151GD16 is listed as a related product with similar application targets but differs in being a non-synchronous buck controller. Designers should verify functional equivalence carefully if considering alternatives.
