Special Purpose Regulators Procurement Notes

Verify current availability status as this component may be subject to discontinuation notices. Confirm exact ordering suffixes match required thermal and packaging specifications. Check for official Product Change Notifications regarding manufacturing site or material updates. Ensure compatibility with existing board layouts due to specific package dimensions.

Special Purpose Regulators Selection Notes

Select this model for systems requiring compliance with Intel IMVP-7 or VR12 architectures. The dual-output capability suits processors needing multiple voltage rails. Consider the 48-TQFN footprint for PCB space constraints. Verify that the 4.5V to 25V input range aligns with system bus voltage levels.

Special Purpose Regulators Part Context

This part belongs to the ISL95831 family of multi-phase controllers. Variants like ISL95831HRTZ-T and ISL95831CHRTZ-T share similar electrical characteristics but differ in temperature grades and packaging formats. The CIRTZ variant specifically targets commercial temperature ranges within the broader R3 controller portfolio.

Special Purpose Regulators Replacement Considerations

ISL95831HRTZ-T and ISL95831CHRTZ-T are related variants within the same product family. Cross-reference pinouts and thermal performance before substitution.
