Product details
Overview
ISL6367HCRZ-T from Renesas (formerly Intersil) is a hybrid digital dual-output PWM controller for Intel VR12.5/VR12/IMVP7-compliant CPU voltage regulation, featuring 6-phase + 1-phase topology, ±0.5% closed-loop system accuracy, EAPP modulation, and SMBus/PMBus/I²C programmability with SVID conflict avoidance.
For engineers reviewing the ISL6367HCRZ-T datasheet, ISL6367HCRZ-T pinout, ISL6367HCRZ-T application, or ISL6367HCRZ-T equivalent, key selection considerations include phase shedding behavior in PSI1/PSI2 modes, DCR/resistor current sensing configuration, droop vs. diode emulation trade-offs, and VR0/VR1 output assignment for core/memory vs. graphics/I/O rails.
Technical Context
The ISL6367HCRZ-T implements two independent PWM outputs: VR0 (1–6 phases, core/memory rail) and VR1 (1 phase, graphics/system agent/I/O rail), each with dedicated current sensing (IMON/IMONS), thermal monitoring (TM/TMS), and remote differential sensing. It supports SerialVID with programmable IMAX, TMAX, BOOT, and ADDRESS OFFSET registers per VR12.5/VR12/IMVP7 compliance.
EAPP modulation enables fast transient response without NVM or firmware; phase shedding is auto-controlled across PSI1 (1–2 phases) and PSI2/PSI3 (1 phase + diode emulation). Current sensing uses either precision resistor or DCR of output inductor, feeding FB pin for droop control and enabling channel-current balancing and average overcurrent protection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output VR12.5/IMVP7 PWM controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IR3567BTRPBF | Full digital architecture with internal NVM; supports higher phase count (up to 8+2) and more granular telemetry resolution | Requires firmware update infrastructure; better suited for cloud-server platforms needing real-time telemetry logging | Choose IR3567BTRPBF when firmware-updatable telemetry and >6-phase scalability are required; ISL6367HCRZ-T preferred for cost-sensitive client platforms |
| RT8803AZSP | Analog-digital hybrid with fixed 4+1 phase topology; lacks SVID conflict-free mode and PSI2/PSI3 diode emulation | Targeted at budget notebooks; no VR12.5 SerialVID support-limited to VR12 base compliance | Choose RT8803AZSP for entry-level designs where VR12.5 features and ultra-low-power modes are not required |
Compared with IR3567BTRPBF and RT8803AZSP, the ISL6367HCRZ-T uniquely balances VR12.5 compliance, zero-firmware operation, and configurable PSI-mode efficiency-making it optimal for client-platform designs where BOM cost, startup simplicity, and light-load efficiency are prioritized over firmware extensibility or maximum phase count.

FAQ
What is the primary function of the ISL6367HCRZ-T in a CPU power delivery system?
The ISL6367HCRZ-T serves as a dual-output hybrid digital PWM controller that manages both the main CPU core/memory rail (VR0, 1–6 phases) and a secondary peripheral rail (VR1, 1 phase) in compliance with Intel VR12.5/VR12/IMVP7 specifications. It executes droop-based voltage positioning, phase shedding, and telemetry reporting via SMBus/PMBus, all without requiring firmware or NVM. Its EAPP modulation ensures rapid transient response critical for modern high-frequency CPUs.
Does the ISL6367HCRZ-T support both DCR and discrete resistor current sensing?
Yes, the ISL6367HCRZ-T supports both DCR-based current sensing using the output inductor's winding resistance and precision shunt resistor sensing. The IMON and IMONS pins accept differential inputs, and internal programmable gain allows calibration for either method. This flexibility enables designers to optimize for cost (DCR) or accuracy (resistor), and both configurations feed the same droop control loop and IOUT telemetry register used by the CPU.
How does the ISL6367HCRZ-T handle low-power states like PSI1 and PSI2?
The ISL6367HCRZ-T responds to the CPU's PSI# signal by entering programmable low-power modes: PSI1 reduces active phases to 1 or 2 for the VR0 rail, while PSI2/PSI3 forces single-phase operation with diode emulation enabled on the active phase. This significantly cuts magnetic core and switching losses, improving light-load efficiency. Upon PSI# de-assertion, dropped phases are restored within microseconds to sustain heavy-load transient performance without compromising regulation.
Is the ISL6367HCRZ-T pin-compatible with other members of the ISL6367 family?
No, the ISL6367HCRZ-T is not pin-compatible with earlier ISL6367 variants such as ISL6367CRZ or ISL6367HRZ due to differences in internal register mapping, PSI mode enablement, and VR12.5-specific SerialVID functionality. The 'H' suffix denotes full VR12.5 compliance including enhanced address offset and TMAX/IMAX programming-requiring validation of schematic and layout against FN7917 Rev 0.00 before substitution.
What thermal monitoring capabilities does the ISL6367HCRZ-T provide?
The ISL6367HCRZ-T provides dual independent thermal monitoring via TM and TMS pins, each accepting an NTC thermistor to measure local temperature near the VR0 and VR1 power stages. Internal ADC digitizes these readings for telemetry reporting and-critically-applies real-time compensation to the current sense circuitry, correcting for DCR drift and ensuring ±0.5% regulation accuracy across –10°C to +105°C ambient. No external ADC or compensation circuitry is required.
