Product details
Overview
ISL6627IRZ-TK from Intersil is a VR11.1/VR12-compatible dual N-channel MOSFET driver for synchronous buck converters, delivering 4A sink current on LGATE, 2A source/sink on UGATE/LGATE, and adaptive shoot-through protection with programmable deadtime. It enables diode emulation during PSI mode for DCM operation in microprocessor core voltage regulators.
For engineers reviewing the ISL6627IRZ-TK datasheet, ISL6627IRZ-TK pinout, ISL6627IRZ-TK application, or ISL6627IRZ-TK equivalent, this page provides verified technical context, exact pin functions, real-world timing behavior (e.g., 8ns rise time, 14ns LGATE turn-off delay), thermal design guidance for the 3x3 DFN package, and validated alternative drivers for VRM designs.
Technical Context
The ISL6627IRZ-TK implements an advanced PWM protocol that detects PSI# commands from VR11.1/VR12 controllers to activate diode emulation-turning off LGATE at inductor zero-crossing to enforce DCM and improve light-load efficiency. Its adaptive shoot-through protection monitors UGATE–PHASE and LGATE voltages to dynamically adjust deadtime, preventing simultaneous conduction while minimizing losses.
It supports fixed propagation delay programming via the TD pin (7–40ns configurable delays), integrates a 36V bootstrap diode with overcharge prevention, and includes a 20kΩ internal high-side gate-to-source resistor to suppress dV/dt-induced self-turn-on. The driver operates from a 5V ±10% VCC supply across –40°C to +85°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 5V ±10% - powers gate drivers and logic; requires low-ESR ceramic decoupling to GND. |
| LGATE Sink Current | 4A - enables fast discharge of large lower MOSFET gates, critical for high-current VRMs. |
| Rise/Fall Times | 8ns (UGATE/LGATE rise), 4ns (LGATE fall) - supports >1MHz switching with minimal transition loss. |
| Propagation Delays | tPDHL = 16ns (adaptive), tPDLL = 14ns - ensures precise timing control between upper/lower FET transitions. |
| Diode Emulation Min ON-Time | 330ns typical - guarantees minimum LGATE conduction during DCM to prevent reverse current. |
| Bootstrap Voltage Rating | 36V (<200ns pulse) - withstands high-voltage transients on BOOT-PHASE node without overstress. |
| Operating Temp Range | –40°C to +85°C - qualified for industrial and computing environments requiring extended thermal margin. |
Pinout & Package
ISL6627IRZ-TK uses a 10-lead 3×3 mm Dual Flat No-lead (DFN) package with exposed thermal pad (EPAD) soldered to GND for enhanced heat dissipation. Pin 1 is UGATE; pin 10 is PHASE; pin 8 is NC; EPAD must be connected directly to PCB ground plane via multiple vias.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| UGATE (Pin 1) | Upper gate drive output | Drives gate of high-side N-MOSFET; referenced to PHASE node; includes 20kΩ internal gate-to-source resistor. |
| BOOT (Pin 2) | Floating bootstrap supply | Connects to bootstrap capacitor (BOOT–PHASE); powers high-side driver; features integrated 36V Schottky diode. |
| TD (Pin 3) | Deadtime programming input | Resistor-to-GND/VCC selects fixed propagation delay (7–40ns); floating enables adaptive mode. |
| PWM (Pin 4) | Control input | Accepts tri-level VR11.1/VR12 PWM signals; detects PSI# for diode emulation activation. |
| GND (Pin 5) | Bias and reference ground | Common return for all signals and power grounds; connects to EPAD for thermal and electrical integrity. |
| LGATE (Pin 6) | Lower gate drive output | 4A sink capability drives large low-side N-MOSFET; turns off during PSI-mode DCM detection. |
| VCC (Pin 7) | Bias supply input | 5V ±10% input; powers internal circuitry and gate drivers; requires local 1µF ceramic decoupling. |
| NC (Pin 8) | No connection | Not internally bonded; must remain unconnected per datasheet. |
| EN (Pin 9) | Enable control | Logic-high (>1.4V) enables driver; logic-low (<1.55V) disables outputs and reduces standby current to 1.15mA. |
| PHASE (Pin 10) | Switching node return | Connects to source of upper MOSFET and drain of lower MOSFET; serves as return path for UGATE drive current. |
Key Features
| Feature | Design Value |
|---|---|
| VR11.1/VR12 Protocol Compliance | Direct interoperability with Intersil VR controllers for PSI#-triggered diode emulation and dynamic mode switching. |
| Adaptive Shoot-Through Protection | Real-time monitoring of UGATE–PHASE and LGATE voltages eliminates need for fixed deadtime tuning across FET variants. |
| Programmable Fixed Deadtime | TD pin resistor selection enables precise optimization of propagation delays (7–40ns) for peak efficiency in specific layouts. |
| Integrated Bootstrap Diode | 36V-rated internal Schottky prevents external diode requirement and blocks overcharge during PHASE node negative swing. |
| High-Side Gate Resistor | 20kΩ on-chip UGATE-to-PHASE resistor suppresses Miller-induced self-turn-on during high dV/dt startup conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck MOSFET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL6622CRZ | Lower temperature grade (0°C to +70°C); no PSI# detection; fixed deadtime only (no adaptive mode). | Limited to commercial-grade computing applications without VR11.1/VR12 controller integration. | Select when cost sensitivity outweighs VR protocol compliance and industrial temp range. |
| MP86942DQKT-LF-Z | Monolithic 2-phase controller + driver; integrates PWM logic, current sensing, and thermal shutdown; no external TD pin. | Replaces discrete controller+driver architecture; targets space-constrained single-board systems. | Choose for simplified BOM count and layout, not for drop-in replacement of ISL6627IRZ-TK in existing VR11.1 designs. |
Compared with ISL6627IRZ-TK, ISL6622CRZ lacks PSI# support and adaptive shoot-through, limiting VR12 compatibility and light-load efficiency; MP86942DQKT-LF-Z integrates control logic but removes flexibility in deadtime tuning and external controller selection-making ISL6627IRZ-TK optimal for modular, high-performance VRM designs requiring protocol fidelity and thermal robustness.

FAQ
What is the maximum switching frequency supported by the ISL6627IRZ-TK?
The ISL6627IRZ-TK supports high-frequency operation up to 1.5MHz, enabled by its 4ns LGATE fall time, 8ns rise times, and sub-30ns propagation delays. Real-world performance depends on MOSFET gate charge and PCB layout; the 3x3 DFN package's low thermal resistance allows sustained operation at 1MHz with proper heatsinking via the EPAD.
Does the ISL6627IRZ-TK require an external bootstrap diode?
No, the ISL6627IRZ-TK integrates a 36V-rated internal bootstrap Schottky diode, eliminating the need for an external diode. This simplifies layout, reduces BOM count, and prevents overcharge during PHASE node negative excursions-critical for reliability in high-dV/dt applications.
How does diode emulation work in the ISL6627IRZ-TK?
In the ISL6627IRZ-TK, diode emulation activates upon detection of a PSI# signal from a VR11.1/VR12 controller. It monitors inductor current zero-crossing and turns off LGATE to prevent reverse current flow, enforcing Discontinuous Conduction Mode (DCM) and improving light-load efficiency by >30% compared to forced CCM operation.
What is the function of the TD pin on the ISL6627IRZ-TK?
On the ISL6627IRZ-TK, the TD pin configures deadtime behavior: floating enables adaptive shoot-through protection, while connecting to GND or VCC via a resistor (100kΩ–910kΩ) selects fixed propagation delays (7–40ns) for UGATE/LGATE transitions-allowing efficiency optimization in specific MOSFET and layout conditions.
Is the ISL6627IRZ-TK RoHS compliant and moisture-sensitive?
Yes, the ISL6627IRZ-TK is Pb-free and RoHS compliant, using 100% matte tin (e3) termination. It is classified as Moisture Sensitivity Level 3 (MSL3) per J-STD-020, requiring bake conditioning if exposed to ambient beyond floor life-details are in Intersil Technical Brief TB363.
