Product details
Overview
ISL6217ACV-T from Renesas (formerly Intersil) is a precision two-phase buck PWM controller IC with integrated half-bridge gate drivers, designed for Intel Pentium IV mobile microprocessor CORE voltage regulation per IMVP-IV™ and IMVP-IV+™ specifications. It delivers 0.700V–1.708V output in 16mV VID steps, supports 250kHz–1MHz per-phase switching, and implements lossless MOSFET rDS(ON) current sensing. It operates in Active, Deep Sleep, and Deeper Sleep modes with programmable droop and soft-start for notebook CPU power delivery.
For engineers reviewing the ISL6217ACV-T datasheet, ISL6217ACV-T pinout, ISL6217ACV-T application, or ISL6217ACV-T equivalent, this page provides verified technical context on IMVP-IV compliance, dual-phase gate drive capability, VID-programmable voltage setpoints, diode emulation in sleep modes, and thermal-limited operation up to 85°C ambient.
Technical Context
The ISL6217ACV-T employs average current mode control combined with input voltage feed-forward for fast transient response in mobile CPU core regulation. Its architecture integrates a 6-bit DAC for VID decoding, proprietary droop compensation using external resistor networks on EA+/SOFT pins, and independent phase control logic enabling dynamic channel reduction from two-phase (Active) to single-phase (Deep/Deeper Sleep).
It features dual high-side/low-side gate drivers with 2A source / 4A sink capability per channel, internal bootstrap diodes, and a PGOOD monitor with 12% blanking window during VID transitions. Protection includes overvoltage (112% of VID), undervoltage (84% of VID), and 32-cycle overcurrent shutdown triggered via OCSET-resistor programming.
Key Specifications

| Protection Thresholds | OVP = 112%, UVP = 84% of VID setpoint; OCP threshold set by OCSET resistor (10–25µA range). |
Pinout & Package
ISL6217ACV-T is housed in a 38-lead TSSOP package (JEDEC MO-173, package drawing M38.173), with 0.5mm pitch, exposed pad not electrically connected, and thermal resistance θJA = 72°C/W on low-thermal-conductivity test board.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-phase buck controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL6227CRZ-T | Dual-output (VCCP/VCCMCH) controller; no VID interface or droop; fixed 1.5V/1.25V outputs. | Designed for memory I/O and chipset rail regulation-not CPU core voltage positioning. | Select only when replacing dedicated VCCP/VCCMCH supplies-not as ISL6217ACV-T substitute. |
| RT8802AGQW | Single-phase IMVP-IV+™ controller; lacks PWRCH pin, phase shedding, and dual-channel gate drivers. | Targeted at entry-level or single-core mobile platforms with lower current requirements (<30A). | Use where cost and simplicity outweigh multi-phase performance; not drop-in for dual-phase designs. |
Compared with ISL6217ACV-T, ISL6227CRZ-T serves non-CPU rails and RT8802AGQW lacks phase-shedding and dual-channel drive-neither supports IMVP-IV™-compliant CPU core regulation with dynamic droop and VID-based voltage scaling.

FAQ
What is the maximum junction temperature rating for the ISL6217ACV-T?
The ISL6217ACV-T has a maximum operating junction temperature of 125°C, as specified in the Absolute Maximum Ratings table. This allows reliable operation in thermally dense notebook VRM layouts when paired with appropriate PCB copper pour and airflow. The device remains fully functional across its −10°C to +85°C ambient range without derating, and thermal shutdown is not implemented-the 125°C limit is a hard reliability boundary.
Does the ISL6217ACV-T support both IMVP-IV™ and IMVP-IV+™ specifications?
Yes, the ISL6217ACV-T is explicitly designed to comply with both IMVP-IV™ and IMVP-IV+™ mobile voltage positioning specifications. It implements all required features including 6-bit VID decoding, programmable droop slope, deep/deeper sleep voltage offsets (98.8% and user-defined), and VID-synchronized PGOOD masking. The datasheet FN9107 Rev 3.00 confirms conformance in the title and Feature list.
How is overcurrent protection configured on the ISL6217ACV-T?
Overcurrent protection on the ISL6217ACV-T is set via a resistor from the OCSET pin to ground. The internal 1.75V reference generates a current (10–25µA) that determines the overcurrent threshold-e.g., a 117kΩ resistor yields 15µA and corresponds to a specific current limit based on ISEN gain. This method avoids external comparators and enables precise, adjustable protection without additional components.
Can the ISL6217ACV-T operate in single-phase mode only?
Yes, the ISL6217ACV-T can be configured for single-phase operation by holding the PWRCH pin LOW. In this mode, only PHASE1/UG1/LG1/ISEN1 are active; PHASE2-related pins enter high-impedance state. This configuration is used during Deep and Deeper Sleep modes to improve light-load efficiency, and it is also valid for Active mode if system current demand is low enough to avoid thermal concerns.
What is the purpose of the SOFT pin on the ISL6217ACV-T?
The SOFT pin on the ISL6217ACV-T controls the slew rate of voltage transitions during soft-start, VID changes, and sleep-mode entries/exits. Connected to ground via a capacitor and to EA+ via a droop resistor, it sources/sinks programmable current (30µA initial, then 130µA) to ramp the error amplifier reference. This ensures controlled CORE voltage ramping per IMVP-IV™ timing requirements and prevents overshoot during mode transitions.
