Product details
Overview
ISL6366CRZ-TK from Renesas Electronics (formerly Intersil) is a dual-output VR12/IMVP7-compliant PWM controller for CPU voltage regulation, featuring 6-phase + 1-phase topology, ±0.5% closed-loop system accuracy over load/line/temperature, and EAPP modulation for fast transient response. It supports coupled-inductor operation, differential remote sensing, and PSI#-driven phase dropping for graphics and system agent rails.
For engineers reviewing the ISL6366CRZ-TK datasheet, ISL6366CRZ-TK pinout, ISL6366CRZ-TK application, or ISL6366CRZ-TK equivalent, key selection criteria include IMON-based current reporting via SVID, programmable PSI1/PSI2/PSI3 phase states, droop control with DCR/resistor sensing, thermal compensation via TMS/TM pins, and compatibility with Intel VR12/IMVP7 microarchitectures.
Technical Context
The ISL6366CRZ-TK implements two independent PWM control loops: VR0 (1–6-phase, core/memory rail) and VR1 (single-phase, graphics/system agent/I/O rail), each with dedicated current sensing, thermal monitoring, and phase management logic. It uses Enhanced Active Pulse Positioning (EAPP) - a patented variable-frequency, feed-forward modulator - to suppress beat-frequency oscillation and improve phase current balance during transients.
It complies fully with Intel VR12/IMVP7 specifications, including SerialVID interface, programmable IMAX/TMAX/BOOT registers, PSI# handshake, and precision droop programming. Current sensing supports both discrete resistor and inductor DCR methods, with integrated thermal compensation digitized from NTC thermistors on TM/TMS pins.

FAQ
What is the primary function of the ISL6366CRZ-TK in a CPU power delivery system?
The ISL6366CRZ-TK serves as a dual-output VR12/IMVP7-compliant PWM controller, managing a 6-phase core/memory rail (VR0) and a 1-phase graphics/system agent/I/O rail (VR1). It delivers precise droop-controlled voltage regulation, real-time current reporting via IMON/SVID, and intelligent phase dropping - all critical for modern Intel CPU power architectures. The ISL6366CRZ-TK enables tight ±0.5% system accuracy and fast transient response through its proprietary EAPP modulation scheme.
Does the ISL6366CRZ-TK support both DCR and resistor-based current sensing?
Yes, the ISL6366CRZ-TK supports both differential DCR sensing across the output inductor and precision shunt resistor sensing. It integrates programmable current sense resistors and applies thermal compensation digitized from NTC thermistors connected to TM/TMS pins - ensuring accurate current measurement across temperature. This dual-sensing capability allows designers to optimize for cost (DCR) or precision (resistor) without changing the ISL6366CRZ-TK footprint or firmware.
How does the ISL6366CRZ-TK implement phase dropping during low-power states?
The ISL6366CRZ-TK uses the PSI# signal from the CPU to enter low-power modes: PSI1 (1- or 2-phase), PSI2/PSI3 (single-phase with diode emulation). Phase dropping is active and controlled internally - no external PWM gating is needed. In PSI2/PSI3, the ISL6366CRZ-TK disables unused high-side FETs and enables diode emulation on active phases to minimize magnetic and switching losses. This preserves transient response headroom while boosting light-load efficiency.
Is the ISL6366CRZ-TK compatible with coupled inductors?
Yes, the ISL6366CRZ-TK explicitly supports coupled-inductor operation on its VR0 (6-phase) output, as confirmed in FN6964 Rev 1.00. Coupled-inductor mode reduces ripple current and improves phase current balance without requiring additional control logic. Configuration is done via dedicated pins and register settings, and the ISL6366CRZ-TK maintains full droop control, current monitoring, and overcurrent protection functionality in this mode - unlike basic phase doublers that lack integrated sensing.
What thermal monitoring capabilities does the ISL6366CRZ-TK provide?
The ISL6366CRZ-TK provides dual independent thermal monitoring via TM and TMS pins, each accepting an NTC thermistor to measure temperature near its respective regulator (VR0 and VR1). Internal ADCs digitize these signals and apply real-time thermal compensation to current sense elements - correcting for DCR drift and improving load-line accuracy. This per-rail thermal intelligence is essential for reliable operation in thermally constrained CPU power stages.
