Product details
Overview
ISL6217ACVZ-T from Renesas Electronics (formerly Intersil) is a precision two-phase buck PWM controller IC with integrated half-bridge gate drivers, designed specifically for Intel Pentium IV mobile microprocessors requiring IMVP-IV™ and IMVP-IV+™ compliant CORE voltage regulation. It delivers 0.700V–1.708V output via 6-bit VID DAC, supports 250kHz–1MHz per-phase switching, and implements lossless MOSFET rDS(ON) current sensing. Its primary system role is dynamic, droop-compensated CORE power delivery in notebook computers.
For engineers reviewing the ISL6217ACVZ-T datasheet, ISL6217ACVZ-T pinout, ISL6217ACVZ-T application, or ISL6217ACVZ-T equivalent, key selection considerations include IMVP-IV/IV+ compliance, dual/single-phase mode transition logic (PWRCH, DSEN#, DRSEN), diode emulation in sleep modes, droop programming via EA+/SOFT/VDROOP, and TSSOP-38 package thermal performance (θJA = 72°C/W).
Technical Context
The ISL6217ACVZ-T employs average current-mode control combined with input voltage feed-forward to achieve fast transient response for CPU load steps. Its proprietary droop architecture uses a programmable current source (27–30µA) sinking from EA+ through an external resistor to generate load-line compensation aligned with IMVP-IV+ specifications.
It integrates dual high-side (UG1/UG2) and low-side (LG1/LG2) gate drivers with 2A source / 4A sink capability, bootstrap diodes, and phase-node sensing (PHASE1/PHASE2, ISEN1/ISEN2). Mode transitions-Active, Deep Sleep (DSV), and Deeper Sleep (DRSV)-are controlled by dedicated logic inputs (DSEN#, DRSEN) and mapped to distinct voltage setpoints with independent soft-start slew control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage Range | 0.700V–1.708V in 16mV VID steps; covers full IMVP-IV/IV+ mobile CPU core voltage range. |
| Switching Frequency | 250kHz–1MHz per phase; set by FSET-to-ground resistor; enables optimization of efficiency vs. size. |
| System Accuracy | ±0.8% over –10°C to +85°C ambient; ensures stable core voltage under thermal stress. |
| Droop Current | 27–30µA typical; sets load-line slope via external resistor for IMVP-IV+ compliant voltage positioning. |
| Overcurrent Protection | 32-cycle shutdown; threshold set by OCSET resistor (10–25µA); prevents MOSFET failure during short-circuit. |
| PGOOD Thresholds | Undervoltage: 84% of VID/DSV/DRSV setpoint; Overvoltage: 112%; latches off converter on fault. |
| Supply Voltage | VDD/VDDP = 5V ±5%; supports standard notebook 5V rail with POR thresholds at 4.20–4.45V (rising). |
Pinout & Package
ISL6217ACVZ-T is housed in a 38-lead Pb-free TSSOP package (M38.173), rated for –10°C to +85°C ambient operation and compatible with SnPb and Pb-free reflow profiles (MSL Level 3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Main IC supply input | +5V power rail input; triggers POR at 4.45V rising; powers internal logic, DAC, and error amplifier. |
| VID0–VID5 | Digital voltage identification inputs | 6-bit parallel bus accepting CMOS logic; selects DAC output voltage per IMVP-IV table (e.g., 0x3F = 0.700V). |
| PWRCH | Power channel select | Logic HIGH enables two-phase operation; LOW forces single-phase mode for light-load efficiency. |
| DSEN#, DRSEN | Sleep mode enable inputs | DSEN# LOW + DRSEN LOW → Deep Sleep; DSEN# LOW + DRSEN HIGH → Deeper Sleep; controls VID override and phase count. |
| UG1/UG2, LG1/LG2 | Gate drive outputs | High-side (UG) and low-side (LG) MOSFET drivers; 2A source / 4A sink; support synchronous rectification. |
| ISEN1/ISEN2 | Current sense inputs | Accepts lossless rDS(ON) voltage drop or discrete sense resistor; feeds average current-mode control loop. |
| EA+, COMP, FB | Error amplifier interface | EA+ = droop-adjusted reference; COMP = amplifier output; FB = remote-sensed core voltage feedback node. |
| PGOOD | Power-good status I/O | Open-drain output pulled low during UV/OV/OC faults; masked during VID/mode transitions to prevent false asserts. |
Key Features
| Feature | Design Value |
|---|---|
| IMVP-IV™ and IMVP-IV+™ Compliance | Fully implements VID decoding, droop compensation, boot/deep/deeper sleep voltage sequencing, and slew rate requirements per spec. |
| Diode Emulation in Sleep Modes | Disables low-side MOSFET conduction during light load, reducing switching losses and improving efficiency below ~1A. |
| Lossless Current Sensing | Uses MOSFET rDS(ON) as current sense element-eliminates power loss and board area of discrete shunt resistors. |
| Programmable Droop & Slew Rate | Droop current (27–30µA) and soft-start ramp (via SOFT capacitor) are externally adjustable to meet exact IMVP-IV+ timing specs. |
| Integrated Gate Drivers & Bootstrap Diodes | Eliminates need for external driver ICs or discrete bootstrap diodes; reduces BOM count and layout complexity. |
Applications

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 controller (VCCP + VCC_MCH); no VID interface or droop; fixed 1.5V/1.8V outputs; no PWRCH/DSEN#/DRSEN logic. | Designed for auxiliary processor rails-not CORE regulation; lacks IMVP-IV+ compliance and phase-shedding capability. | Select only when replacing companion rails-not as direct ISL6217ACVZ-T substitute; requires separate CORE controller. |
| RT8803GQW | Single-phase IMVP-8 controller; 3–24V input; supports 0.25–1.52V output; no DSV/DRSV pins; different VID mapping and protection thresholds. | Targets newer Intel ULV CPUs (e.g., Core i-series); incompatible VID table, sleep logic, and droop architecture. | Use only for new designs targeting IMVP-8; not drop-in or functionally equivalent for IMVP-IV+ systems. |
Compared with ISL6217ACVZ-T, ISL6227CRZ serves auxiliary rails without VID or droop, while RT8803GQW targets newer IMVP-8 CPUs with incompatible control logic-neither replicates the precise IMVP-IV+ phase-shedding, deep-sleep voltage positioning, or lossless current sensing of the ISL6217ACVZ-T.

FAQ
What is the operating temperature range for the ISL6217ACVZ-T?
The ISL6217ACVZ-T is specified for ambient operation from –10°C to +85°C, with a maximum junction temperature of 125°C. Its thermal resistance θJA is 72°C/W in the TSSOP-38 package, enabling reliable performance in thermally constrained notebook chassis when properly heatsinked.
How does the ISL6217ACVZ-T implement lossless current sensing?
The ISL6217ACVZ-T senses channel current by measuring the voltage drop across the high-side MOSFET's rDS(ON) using ISEN1/ISEN2 inputs-eliminating external sense resistors. This method preserves efficiency and reduces PCB area, while feeding accurate current data into its average current-mode control loop.
Can the ISL6217ACVZ-T operate in single-phase mode?
Yes-the ISL6217ACVZ-T dynamically switches between two-phase (Active mode) and single-phase (Deep/Deeper Sleep modes) based on logic states applied to PWRCH, DSEN#, and DRSEN pins. This phase shedding improves light-load efficiency without requiring firmware intervention.
What protections does the ISL6217ACVZ-T provide for the CPU power rail?
The ISL6217ACVZ-T provides overvoltage (112% of setpoint), undervoltage (84% of setpoint), and overcurrent (32-cycle shutdown) protection. All faults force PGOOD low and latch the controller off until EN is toggled or VDD is cycled-safeguarding the CPU from destructive voltage excursions.
How is the "Droop" voltage programmed on the ISL6217ACVZ-T?
Droop is programmed by connecting an external resistor between EA+ and VSS. The ISL6217ACVZ-T sources a precise 27–30µA current (IDROOP) into this resistor, generating a load-proportional voltage drop that offsets the reference-enabling IMVP-IV+ compliant voltage positioning.
