Product details
Overview
ISL6217CVZ from Intersil is a precision two-phase buck PWM controller with integrated half-bridge gate drivers, designed for Intel IMVP-IV™ and IMVP-IV+™ mobile voltage positioning in notebook CPU core regulation. 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 and programmable droop for dynamic load response in high-performance mobile platforms.
For engineers reviewing the ISL6217CVZ datasheet, ISL6217CVZ pinout, ISL6217CVZ application, or ISL6217CVZ equivalent, key selection considerations include IMVP-IV/IV+ compliance, dual/single-phase mode transition via PWRCH, remote sensing (VSEN), PGOOD monitoring with VID-change blanking, and thermal-limited operation up to 85°C ambient in 38-lead TSSOP.
Technical Context
The ISL6217CVZ employs average current mode control combined with input voltage feed-forward to achieve fast transient response under dynamic CPU load steps. Its architecture integrates a 6-bit VID DAC, dual-channel PWM generators with 180° phase shift, and dedicated logic inputs (DSEN#, DRSEN) for Active/Deep/Deeper Sleep mode sequencing per IMVP-IV+ specification.
It features a programmable soft-start ramp controlled by SOFT pin current sourcing/sinking (30µA + 100µA), droop compensation via EA+/SOFT/VDROOP network, and overcurrent protection triggered after 32 consecutive cycles exceeding the OCSET threshold. Protection includes OVP (112% of VID), UVP (84% of VID), and latched-off shutdown with PGOOD forced low.
Key Specifications

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 | Successor with enhanced OVP/UVP thresholds (110%/90%), improved thermal shutdown, and tighter DAC linearity (±0.5%). | Designed for newer IMVP-IV+ revisions; supports higher-frequency CPUs with faster VID slew requirements. | Select ISL6217A for new designs requiring extended lifecycle support and tighter accuracy; ISL6217CVZ remains valid for legacy IMVP-IV platforms. |
| RT8802A | Single-chip 2-phase controller with integrated MOSFET drivers; supports 300kHz–1.5MHz switching but lacks native IMVP-IV VID decode. | Requires external VID translation logic; optimized for cost-sensitive consumer notebooks rather than Intel reference designs. | Choose RT8802A only when IMVP-IV compliance is not mandatory and BOM cost reduction outweighs VID integration loss. |
Compared with ISL6217A, the ISL6217CVZ offers full IMVP-IV timing and VID mapping but with looser OVP/UVP margins and older thermal specs; versus RT8802A, it provides native Intel protocol support at the expense of flexibility in non-Intel platforms.

FAQ
What is the maximum ambient operating temperature for the ISL6217CVZ?
The ISL6217CVZ is rated for -10°C to +85°C ambient temperature operation, with a maximum junction temperature of 125°C. Its 38-lead TSSOP package has a thermal resistance θJA of 72°C/W, making it suitable for thermally dense notebook motherboard layouts where airflow is limited. Derating is not required within this range when PCB copper area meets recommended layout guidelines.
Does the ISL6217CVZ support both IMVP-IV and IMVP-IV+ specifications?
Yes, the ISL6217CVZ is explicitly designed to comply with both Intel IMVP-IV™ and IMVP-IV+™ mobile voltage positioning specifications. It implements all required features including 6-bit VID decoding, programmable droop, boot/deep/deeper sleep voltage programming (STV/DSV/DRSV), and precise VID transition timing with PGOOD blanking-validated in the December 2006 datasheet FN9089.3.
How does the ISL6217CVZ implement lossless current sensing?
The ISL6217CVZ uses the RDS(ON) of the synchronous MOSFETs as the current sense element via its ISEN1 and ISEN2 pins. This eliminates discrete current-sense resistors, reducing power loss, board space, and thermal hotspots. The controller scales the sensed voltage to match internal current thresholds, enabling accurate overcurrent detection and average current mode control without added components.
What is the function of the PWRCH pin on the ISL6217CVZ?
The PWRCH pin on the ISL6217CVZ controls the number of active power phases: a logic HIGH enables two-phase operation for full-load performance, while a logic LOW forces single-phase operation to improve light-load efficiency during Deep and Deeper Sleep modes. It is typically tied to DSEN# (STP_CPU#) to automatically scale phase count with CPU activity state.
Can the ISL6217CVZ be used in new designs today?
The ISL6217CVZ is marked "NOT RECOMMENDED FOR NEW DESIGNS" in its official ordering table, with ISL6217A cited as the preferred substitute. While fully functional and supported for legacy repair and continuity, new designs should evaluate ISL6217A for improved accuracy, updated protection thresholds, and longer-term manufacturer support-though ISL6217CVZ remains viable where IMVP-IV compliance and existing qualification are mandatory.
