CS5151GD16

Special Purpose Regulators Overview

The CS5151GD16 is a CPU-specific non-synchronous buck controller designed for Intel Pentium II and Pro processors. It operates within an input voltage range of 4.25V to 16V and provides one output. The device is housed in a 16-SOIC package with a width of 3.90mm. It supports a junction temperature range from 0°C to 150°C.

Special Purpose Regulators Feature Summary

• Designed specifically as a controller for Intel Pentium II and Pro processor voltage regulation.

Special Purpose Regulators Applications

• Intel Pentium II processor power systems
• Intel Pentium Pro processor power systems

Special Purpose Regulators Procurement Notes

Verify component status carefully, as the part is listed as discontinued or no longer provided by distributors. Confirm availability through official onsemi channels or authorized legacy supply networks before design finalization. Ensure all technical documentation references are current and match the specific GD16 suffix requirements for your application.

Special Purpose Regulators Selection Notes

Select this component only if the target design requires compatibility with Intel Pentium II or Pro architectures. Verify that the 16-SOIC package dimensions fit the PCB layout constraints. Confirm that the input voltage range of 4.25V to 16V aligns with the system power rail specifications.

Special Purpose Regulators Part Context

This component belongs to the specialized PMIC category focusing on CPU voltage regulation. It is part of onsemi's portfolio addressing legacy high-performance computing platforms. The device functions as a dedicated controller rather than a general-purpose regulator, targeting specific processor power delivery needs.

Special Purpose Regulators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, alternative solutions require careful architectural review and potential redesign of the power stage components.
