ISL6336CRZ

Special Purpose Regulators Overview

The ISL6336CRZ is a dual switching controller designed for VR12 and IMVP7 compliant voltage regulator applications. It integrates six-phase PWM outputs to regulate microprocessor core or memory voltages, alongside a single-phase PWM output for peripheral rails such as graphics, system agent, or processor I/O. The device utilizes Enhanced Active Pulse Positioning (EAPP) modulation to achieve fast transient response with reduced output capacitance. It operates within a 4.75 V to 5.25 V input range and is housed in a 60-lead HVQCCN package measuring 7 mm by 7 mm.

Special Purpose Regulators Feature Summary

• Dual PWM architecture combining six-phase control for core/memory loads with single-phase control for peripheral supplies
• Enhanced Active Pulse Positioning (EAPP) modulation scheme for optimized transient performance
• Compliance with Intel VR12 and IMVP7 voltage regulator specifications

Special Purpose Regulators Applications

• Microprocessor core voltage regulation
• Memory voltage regulator design
• Graphics power supply control
• System agent voltage management
• Processor I/O voltage regulation

Special Purpose Regulators Procurement Notes

Verify the specific suffix 'CRZ' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the selected variant matches the required lead frame material and moisture sensitivity level for your assembly process. Cross-reference the ordering information with official Renesas documentation to avoid discrepancies between distributor listings and actual component specifications.

Special Purpose Regulators Selection Notes

Select this component when designing systems requiring simultaneous high-current core processing and dedicated peripheral rail management under VR12 standards. The integrated EAPP technology reduces the bill of materials by minimizing external output capacitors. Evaluate thermal requirements based on the 60-lead QFN package dimensions and ensure the PCB layout supports the high-frequency switching characteristics inherent to the multi-phase architecture.

Special Purpose Regulators Part Context

This part belongs to the Intersil/Renesas family of advanced voltage regulator controllers. It succeeds earlier generations by supporting stricter transient requirements defined in the VR12 specification. The dual-channel design consolidates multiple discrete controller functions into a single package, simplifying board space constraints for modern high-pin-count processors and complex server architectures.
