Product details
Overview
ISL6217CVZ-T from Intersil is a precision two-phase buck PWM controller with integrated half-bridge gate drivers, designed for Intel IMVP-IV™/IMVP-IV+™ mobile CPU core voltage regulation in notebook computers. It delivers 0.700V–1.708V output via 6-bit VID DAC, supports 250kHz–1MHz per-phase switching, and implements lossless RDS(ON) current sensing with programmable droop compensation.
For engineers reviewing the ISL6217CVZ-T datasheet, ISL6217CVZ-T pinout, ISL6217CVZ-T application, or ISL6217CVZ-T equivalent, key selection criteria include IMVP-IV compliance, dual/single-phase dynamic mode switching via PWRCH, remote sensing (VSEN), PGOOD monitoring with VID-blanking, and thermal-aware droop-based load-line regulation.
Technical Context
The ISL6217CVZ-T employs average current-mode control combined with input voltage feed-forward to achieve fast transient response for high-performance Pentium IV mobile processors. Its architecture integrates dual PWM channels with 180° interleaved timing, internal bootstrap diodes, and dedicated logic inputs (DSEN#, DRSEN) for seamless transition between Active, Deep Sleep, and Deeper Sleep modes.
It features a precision 1.75V internal reference, 0.8% system accuracy over temperature, and proprietary droop current source (26.5–29.5µA) that scales with load to maintain stable voltage positioning. The SOFT pin controls slew rate during VID changes and soft-start using dual current sources (30µA + 100µA), meeting IMVP-IV+™ timing requirements for all operating modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Package | 38-lead TSSOP (M38.173); RoHS-compliant Pb-free plus anneal finish; θJA = 72°C/W for notebook thermal constraints. |
Pinout & Package
ISL6217CVZ-T is housed in a 38-lead thin shrink small-outline package (TSSOP), optimized for high-density notebook motherboard layouts and compatible with standard Pb-free reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Primary IC supply input | +5V ±5% power rail; POR threshold at 4.45V rising ensures reliable startup before enabling PWM outputs. |
| PWRCH | Phase count selection | Logic HIGH enables two-phase operation; LOW forces single-phase mode for light-load efficiency in Deep/Deeper Sleep. |
| VID0–VID5 | Digital voltage identification inputs | 6-bit parallel interface directly maps to Intel IMVP-IV™ VID codes; no internal pull-up/down required. |
| VSEN | Remote voltage sense input | Connects to CPU VCC_CORE pad to compensate for IR drop across PCB traces and improve regulation accuracy. |
| PGOOD | Power-good status I/O | Open-drain output pulled low during OVP/UVP/OCP; also accepts external PGOOD signals from Vccp/Vcc_mch during startup. |
| UG1/UG2, LG1/LG2 | Gate drive outputs | Integrated 2A source / 4A sink capability per low-side driver; supports fast turn-on/off of modern low-RDS(ON) MOSFETs. |
| ISEN1/ISEN2 | Channel current sense inputs | Differential inputs for lossless current sensing via high-side MOSFET RDS(ON); enables per-phase current balancing. |
| EA+, COMP, FB | Error amplifier interface | EA+ sets reference; FB is inverting input; COMP is error amp output - forms closed-loop regulation with external compensation network. |
Key Features
| Feature | Design Value |
|---|---|

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 |
|---|---|---|---|
| ISL6217A | Enhanced revision with improved thermal performance and updated IMVP-IV+™ timing compliance; same pinout and VID mapping. | Recommended for new designs requiring extended lifecycle support and tighter transient response specs. | Select ISL6217A when designing for long-term availability and latest IMVP-IV+™ revisions; not drop-in for legacy BIOS with strict ISL6217 timing assumptions. |
| RT8802A | Single-chip 2-phase controller with integrated MOSFET drivers; supports IMVP-6/7 but lacks native IMVP-IV™ VID decoding logic. | Suitable for newer platforms migrating from IMVP-IV™ to IMVP-6/7; requires VID translation firmware or external logic. | Choose RT8802A only if upgrading platform architecture; incompatible with unmodified IMVP-IV™ BIOS and VID command sequences. |
Compared with ISL6217CVZ-T, ISL6217A offers verified IMVP-IV+™ timing enhancements and longer manufacturer support, while RT8802A targets next-generation voltage specs but requires system-level redesign to replace ISL6217CVZ-T in IMVP-IV™-compliant notebooks.

FAQ
What is the primary function of the ISL6217CVZ-T in a notebook power system?
The ISL6217CVZ-T serves as the core voltage regulator controller for Intel Pentium IV mobile processors, implementing IMVP-IV™/IMVP-IV+™ voltage positioning with two-phase buck topology, lossless current sensing, and dynamic phase shedding. It directly manages VCC_CORE regulation, sleep-state transitions, and protection functions - making it central to power integrity in compliant notebook designs.
Does the ISL6217CVZ-T support both single-phase and two-phase operation?
Yes, the ISL6217CVZ-T dynamically switches between single-phase and two-phase operation based on the logic level applied to the PWRCH pin. It operates in two-phase mode during Active state for high-current loads and automatically reduces to single-phase in Deep Sleep and Deeper Sleep modes - improving light-load efficiency without software intervention.
How does the ISL6217CVZ-T implement "lossless" current sensing?
The ISL6217CVZ-T uses the RDS(ON) of the high-side MOSFETs as the current-sense element, eliminating the need for discrete shunt resistors. It samples voltage across the MOSFET channel via ISEN1/ISEN2 pins and scales the signal internally - reducing board area, power loss, and BOM cost while maintaining accurate per-phase current measurement for balancing and OCP.
What are the voltage setpoint sources for Active, Deep Sleep, and Deeper Sleep modes in the ISL6217CVZ-T?
In Active mode, ISL6217CVZ-T regulates to the VID-programmed DACOUT voltage minus droop. In Deep Sleep mode (DSEN# = LOW, DRSEN = LOW), it regulates to the externally programmed DSV voltage minus droop. In Deeper Sleep mode (DSEN# = LOW, DRSEN = HIGH), it regulates to the DRSV voltage minus droop - all three setpoints are independently adjustable via resistor dividers referenced to DACOUT or OCSET's 1.75V internal reference.
Is the ISL6217CVZ-T pin-compatible with the ISL6217A?
Yes, the ISL6217CVZ-T is pin-compatible with the ISL6217A and shares identical pinout, package (38-lead TSSOP), and basic functionality. However, ISL6217A includes minor electrical improvements - including enhanced thermal performance and refined IMVP-IV+™ timing margins - and is recommended for new designs due to its extended lifecycle and updated qualification.
