Product details
Overview
ISL6217ACVZ 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. Used in notebook computer power delivery systems requiring dynamic load response and multi-mode efficiency optimization.
For engineers reviewing the ISL6217ACVZ datasheet, ISL6217ACVZ pinout, ISL6217ACVZ application, or ISL6217ACVZ equivalent, key selection considerations include IMVP-IV/IV+ compliance, dual/single-phase mode switching via PWRCH, diode emulation in sleep modes, droop-based voltage positioning, and 38-lead TSSOP package compatibility with thermal constraints up to 125°C junction temperature.
Technical Context
The ISL6217ACVZ employs average current mode control combined with input voltage feed-forward for fast transient response in high-performance CPU core supplies. Its architecture integrates a 6-bit DAC for VID decoding, programmable "Droop" compensation via EA+/SOFT/DRSV/DSV pins, and independent phase control logic enabling dynamic channel reduction from two-phase (Active) to single-phase (Deep/Deeper Sleep).
Protection is implemented through cycle-by-cycle overcurrent detection (32-cycle shutdown), ±12% overvoltage/undervoltage thresholds relative to VID setpoint, and PGOOD monitoring with blanking during VID and mode transitions. Gate drive outputs support 2A source / 4A sink capability per low-side driver and include internal bootstrap diodes.

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 | Dual-output (VCCP/VCCMCH) regulator only; no VID decoding, no droop, no PWRCH scaling; lacks CORE-specific IMVP-IV+ features. | Designed for auxiliary processor rails-not CORE voltage; cannot replace ISL6217ACVZ in primary CPU VRM. | Select only for companion rail regulation; not a functional substitute for ISL6217ACVZ in CORE applications. |
| RT8803AZSP | Single-phase IMVP-IV+ controller; no PWRCH pin; fixed 500kHz switching; no diode emulation; lower integration (external gate drivers required). | Suitable for low-power Atom/Celeron platforms; insufficient phase count and feature set for Pentium IV-class loads. | Consider only for cost-sensitive, low-current designs where two-phase capability and advanced sleep modes are unnecessary. |
Compared with ISL6217ACVZ, ISL6227CRZ serves auxiliary rails only and lacks VID/droop/PWRCH functionality, while RT8803AZSP offers reduced phase count and no dynamic scaling-making ISL6217ACVZ uniquely suited for high-performance mobile CPU core regulation with full IMVP-IV+ compliance.

FAQ
What is the maximum junction temperature rating for the ISL6217ACVZ?
The ISL6217ACVZ has a maximum operating junction temperature of 125°C, with a thermal resistance θJA of 72°C/W in its 38-lead TSSOP package. This allows sustained operation in thermally dense notebook chassis when mounted on standard FR-4 PCBs with moderate copper pour. Derating is recommended above 100°C ambient to maintain reliability over lifetime.
Does the ISL6217ACVZ support both IMVP-IV and IMVP-IV+ specifications?
Yes, the ISL6217ACVZ is explicitly designed to comply with both IMVP-IV™ and IMVP-IV+™ specifications, including VID decoding (0.700V–1.708V in 16mV steps), droop-based voltage positioning, deep/deeper sleep mode sequencing, and PGOOD timing requirements. The datasheet FN9107 confirms full conformance to both standards.
How does the ISL6217ACVZ implement lossless current sensing?
The ISL6217ACVZ uses the MOSFET's intrinsic rDS(ON) as a current-sense element by measuring the voltage drop across the low-side FET during conduction. This eliminates the need for external shunt resistors, reducing board area, power loss, and cost. ISEN1/ISEN2 inputs condition this signal for per-phase current balancing and overcurrent protection.
Can the ISL6217ACVZ operate in single-phase mode only?
Yes-the ISL6217ACVZ can be configured for single-phase operation by holding the PWRCH pin LOW. It defaults to two-phase in Active mode but automatically switches to single-phase in Deep and Deeper Sleep modes when PWRCH is tied to DSEN#. This reduces gate drive losses and improves light-load efficiency without external reconfiguration.
What is the purpose of the DSV and DRSV pins on the ISL6217ACVZ?
The DSV (Deep Sleep Voltage) and DRSV (Deeper Sleep Voltage) pins allow external programming of sleep-mode output voltages. DSV is typically set to 98.8% of the VID voltage via a resistor divider from DACOUT; DRSV is set independently from the 1.75V OCSET reference. Both enable precise, IMVP-IV+ compliant voltage scaling during low-power states.
