ISL6307BCRZ

DC DC Switching Controllers Overview

The ISL6307BCRZ is a six-phase VR11 PWM controller designed for microprocessor core voltage regulation. It drives up to six synchronous-rectified buck channels in parallel using interleaved timing to multiply channel ripple frequency and reduce input/output ripple currents. The device supports precision RDS(ON) or DCR differential current sensing. It accepts an 8-bit VID code for voltage selection and operates with a supply voltage range of 4.75 V to 5.25 V. The maximum switching frequency is 1 MHz, and it utilizes pulse width modulation control.

DC DC Switching Controllers Feature Summary

• Supports multiphase buck converter architecture with interleaved timing to minimize ripple currents
• Capable of precision RDS(ON) or DCR differential current sensing for accurate load balancing
• Integrates 8-bit VID code interface for direct microprocessor voltage identification

DC DC Switching Controllers Applications

• Microprocessor core voltage regulation
• High-performance server power supplies
• Graphics processing unit (GPU) power delivery

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'BCRZ' against official Renesas documentation to confirm tape-and-reel packaging and RoHS compliance status. Ensure the component matches the VR11 specification requirements for your target application. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current lifecycle status before procurement.

DC DC Switching Controllers Selection Notes

Select this controller when designing high-current, low-voltage power stages for processors requiring precise phase balancing. The choice depends on the need for integrated current sensing options and VID compatibility. Evaluate thermal management requirements for the QFN package and ensure the external components support the 1 MHz switching frequency for optimal efficiency and size reduction.

DC DC Switching Controllers Part Context

This component belongs to the Intersil ISL6307 family, now managed by Renesas Electronics following the acquisition. The series includes variants such as the ISL6307B and ISL6307C, which share similar six-phase control architectures but may differ in specific electrical characteristics or feature sets. The ISL6307BCRZ represents a specific packaged version within this product line.

DC DC Switching Controllers Replacement Considerations

Consult Renesas Product Legacy Documents for confirmed substitutes. The ISL6307B and ISL6307C are related family members; verify functional equivalence before substitution.
