ISL6323CRZ-T

Special Purpose Regulators Overview

The ISL6323CRZ-T is a switching controller manufactured by Renesas Electronics Corporation, designed for power management applications. It functions as a 4-phase controller with two dedicated drivers and supports two PWM outputs alongside a Northbridge interface. The device operates within an input voltage range of 5V to 12V and provides a maximum output voltage of 2V. It is housed in a 48-VFQFN package with exposed pad, measuring 7x7 mm. The component supports current mode PWM control and is rated for operation between 0°C and +70°C. It complies with RoHS3 standards and has a moisture sensitivity level of 3.

Special Purpose Regulators Feature Summary

• Integrates four-phase control logic with two independent driver channels for efficient power distribution.
• Supports dual PWM outputs combined with a dedicated Northbridge interface for complex system requirements.
• Utilizes current mode pulse width modulation architecture for precise regulation and stability.

Special Purpose Regulators Applications

• AMD SVI (Serial Voltage Interface) controller implementations
• Northbridge power supply regulation circuits
• Multi-phase DC-DC converter systems requiring integrated control

Special Purpose Regulators Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm package integrity and moisture barrier packaging validity given the MSL 3 rating. Cross-reference datasheet revisions to ensure compatibility with existing design specifications. Check for alternative sourcing options as standard availability may be limited.

Special Purpose Regulators Selection Notes

Select this component for designs requiring integrated multi-phase control with Northbridge support. Ensure input voltage constraints align with the 5V to 12V operational range. Verify thermal management capabilities for the 48-QFN package within the specified temperature limits. Consider pinout compatibility if replacing legacy Intersil variants.

Special Purpose Regulators Part Context

Part of the ISL6323A series from Renesas/Intersil, focusing on high-performance CPU power management. It bridges the gap between simple regulators and complex digital controllers by offering analog multi-phase control with specific interface protocols. The series targets desktop and server platforms requiring stable core voltages.

Special Purpose Regulators Replacement Considerations

ISL6323ACRZ-T serves as a direct functional substitute within the same series. Verify pin compatibility and electrical parameters before substitution. Consult official cross-reference lists for any updated revisions or enhanced variants offered by Renesas.
