ISL6336DIRZ

Special Purpose Regulators Overview

The ISL6336DIRZ is a VR11.1 compliant, six-phase PWM controller designed for high-performance processor voltage regulation. It operates with a switching frequency range of 80 kHz to 1 MHz and supports output voltages from 500 mV to 1.6 V. The device manages up to 200 A of load current across its interleaved synchronous-rectified buck channels. It features phase dropping capabilities and droop disabled modes for optimized efficiency under varying loads. Operating within a temperature range of -40°C to +85°C, it is housed in a 48-VFQFN exposed pad package.

Special Purpose Regulators Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified partners. Confirm the specific suffix 'DIRZ' matches the required 48-QFN package variant. Check for RoHS compliance documentation as indicated in official specifications. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly.

Special Purpose Regulators Selection Notes

Select this controller for applications requiring strict VR11.1 compliance and multi-phase power distribution. Evaluate thermal performance given the 48-QFN package constraints. Consider the 80 kHz to 1 MHz frequency range for inductor sizing and EMI filtering requirements. Verify compatibility with the target processor's VID (Voltage ID) interface signals.

Special Purpose Regulators Part Context

This component belongs to the ISL6336B/D series of multiphase controllers from Renesas/Intersil. These devices are engineered for demanding computing environments where transient response and efficiency are critical. The series integrates digital control algorithms to manage complex power sequencing and protection mechanisms for modern microprocessors.

Special Purpose Regulators Replacement Considerations

The ISL6336BIRZ-T is a related variant within the same family. Verify pinout compatibility and specific feature differences such as phase dropping configuration before substitution. Consult official cross-reference guides for confirmed equivalent parts.
