CS5161HGDR16

Special Purpose Regulators Overview

The CS5161HGDR16 is a special purpose voltage regulator controller designed for Intel Pentium III processors. It operates within an input voltage range of 4.25V to 20V and provides one output channel in a 16-SOIC package. Key electrical specifications include a 1.0% output tolerance, onboard 5-bit DAC, VCC monitor, programmable soft start, and short circuit protection.

Special Purpose Regulators Feature Summary

• Integrated 5-bit digital-to-analog converter (DAC) for precise voltage adjustment
• Built-in short circuit protection and VCC monitoring capabilities
• Programmable soft start functionality to manage inrush current

Special Purpose Regulators Applications

• Intel Pentium III CPU voltage regulation
• Special purpose power supply controllers
• Motherboard VRM designs

Special Purpose Regulators Procurement Notes

Verify the component status as obsolete before procurement planning. Confirm compatibility with legacy Intel Pentium III architectures. Ensure sourcing channels provide authentic units from onsemi or authorized distributors to avoid counterfeit risks associated with discontinued parts.

Special Purpose Regulators Selection Notes

Select this controller specifically for legacy systems requiring Intel Pentium III compliance. The 16-SOIC package and single-output configuration suit space-constrained motherboard layouts. Consider the integrated protection features for robust system reliability without external components.

Special Purpose Regulators Part Context

This part belongs to onsemi's special purpose regulators category, historically utilized in computing infrastructure. It serves as a dedicated solution for processor core voltage regulation, distinct from general-purpose DC-DC controllers due to its specific interface and feature set tailored for CPU power management.

Special Purpose Regulators Replacement Considerations

As the CS5161HGDR16 is marked obsolete, verify if the CS5166GDWR16 serves as a functional substitute. Check pinout compatibility and software configuration requirements when migrating to alternative synchronous CPU controllers.
