Special Purpose Regulators Procurement Notes

Verify component status carefully, as distribution records indicate this specific part number may be discontinued or no longer actively provided by major distributors. Confirm availability through official onsemi channels or authorized partners before finalizing procurement plans. Ensure compatibility with existing board designs given its specialized nature for Pentium II platforms.

Special Purpose Regulators Selection Notes

Select this component only when designing for or servicing systems requiring precise power management for Intel Pentium II processors. The 5-bit resolution and synchronous NFET control are key differentiators. Consider the 16-SOIC package constraints and 12V input requirement during schematic capture. Verify that the dual-output capability aligns with the target processor's voltage rail specifications.

Special Purpose Regulators Part Context

This device belongs to onsemi's portfolio of special purpose regulators tailored for high-performance microprocessors. It sits within the category of synchronous CPU buck controllers, distinct from general-purpose DC-DC converters. The CS5165A series was developed to address the specific transient response and efficiency demands of early 1990s/early 2000s high-speed CPUs like the Pentium II.

Special Purpose Regulators Replacement Considerations

Public confirmed substitute part numbers include CS5165GDW16 and CS5165AGDWR16G. Verify pinout and electrical parameter compatibility before substitution.
