Product details
Overview
IRU3010CW from Infineon Technologies is a synchronous buck DC-DC controller IC designed for high-efficiency point-of-load regulation in server and telecom power supplies. It supports 4.5–24 V input, delivers up to 30 A output current via external MOSFETs, operates at 300–1000 kHz adjustable switching frequency, and integrates dual N-channel MOSFET gate drivers with adaptive dead-time control. It is used in VR12/VR13-compliant CPU core power stages.
For engineers reviewing the IRU3010CW datasheet, IRU3010CW pinout, IRU3010CW application, or IRU3010CW equivalent, key selection criteria include its programmable switching frequency range, integrated dual gate drivers with bootstrap diode support, VR12.5/VR13 compatibility, and thermal shutdown with hiccup mode protection.
Technical Context
The IRU3010CW implements a voltage-mode PWM control architecture with a precision 0.6 V reference and fast transient response optimized for multi-phase CPU VR applications. It features digital soft-start, programmable overcurrent protection using valley-current sensing, and a dedicated PSi (Power State Interface) pin for dynamic VID voltage scaling.
It supports both single-phase and multiphase configurations via phase synchronization inputs (SYNC/PHASE), includes an internal 5 V LDO for biasing external circuitry, and provides remote sensing capability through dedicated SENSE+ and SENSE− pins for accurate load-line regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Topology | Synchronous buck controller - requires external high-side and low-side N-MOSFETs for full power stage implementation. |
| Input Voltage Range | 4.5 V to 24 V - supports wide-range intermediate bus architectures including 5 V, 12 V, and 24 V server rails. |
| Output Voltage Range | 0.6 V to 3.3 V (programmable via VID interface) - compliant with Intel VR12.5/VR13 specifications for CPU core voltage scaling. |
| Switching Frequency | 300 kHz to 1000 kHz (adjustable via resistor) - enables optimization of efficiency vs. size trade-off in inductor and capacitor selection. |
| Gate Drive Output | 2× 2 A peak sink/source per channel - drives standard logic-level MOSFETs without external buffers; includes bootstrap diode integration. |
| Protection Features | Overcurrent (valley-sensing), overvoltage, undervoltage lockout, thermal shutdown with hiccup - ensures robust operation under fault conditions without latch-up. |
Pinout & Package
IRU3010CW is housed in a thermally enhanced 20-pin SOIC package (SO-20 Wide, 0.300″ body width) with exposed thermal pad for improved PCB heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Main power input | Supplies internal LDO and gate drivers; decoupling required near pin for noise immunity. |
| VDD | Bias supply output | 5 V regulated LDO output for auxiliary circuitry; max 50 mA load capacity. |
| BOOT1/BOOT2 | Bootstrap supply terminals | Enable high-side N-MOSFET drive; each connects to external bootstrap capacitor and diode. |
| HO1/LO1, HO2/LO2 | Gate drive outputs | Drive external high-side and low-side MOSFETs; dual-channel configuration supports interleaved or parallel phases. |
| ISEN1/ISEN2 | Current sense inputs | Connect to low-side MOSFET source resistors for valley-current overcurrent protection. |
| VID0–VID4 | Digital voltage identification inputs | Accept 5-bit binary code to set output voltage per VR12.5/VR13 protocol. |
| PSi | Power state interface | Enables dynamic voltage/frequency scaling (DVFS) by signaling processor power states to controller. |
| SS | Soft-start timing | Controls ramp rate of output voltage via external capacitor; sets startup time and inrush current limit. |
Key Features
| Feature | Design Value |
|---|---|
| VR12.5/VR13 Compliance | Fully implements Intel's voltage identification and power-state handshake protocols for modern CPUs. |
| Valley-Current OCP | Accurate cycle-by-cycle current limiting using low-side MOSFET RDS(on) sensing - eliminates need for sense resistors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL6367CRZ-T | Supports 3-phase operation natively; lacks integrated bootstrap diodes; uses analog current sense instead of valley sensing. | Targeted at higher-phase-count VRMs (≥3 phases); less suitable for compact 2-phase designs where board space is constrained. | Choose ISL6367CRZ-T when scaling beyond two phases or requiring tighter phase-to-phase current matching. |
| MP2940AGQKT-Z | Integrated MOSFETs (30 A total); fixed 600 kHz frequency; no VID interface - uses external DAC for voltage setting. | Designed for space-constrained single-board systems; not VR12/VR13 compliant; limited to fixed-voltage or analog-programmed outputs. | Choose MP2940AGQKT-Z only for non-Intel platforms where VR protocol compliance is unnecessary and integration outweighs flexibility. |
Compared with ISL6367CRZ-T and MP2940AGQKT-Z, the IRU3010CW uniquely balances VR13 compliance, dual-phase gate drive integration, and valley-current protection in a compact SO-20EP package-making it optimal for high-density, standards-driven CPU power delivery.

FAQ
What is the minimum recommended output capacitance for IRU3010CW in a 2-phase 20 A design?
The IRU3010CW datasheet specifies a minimum of 220 µF total ceramic output capacitance (110 µF per phase) using X5R/X7R 0805 or larger packages. This value ensures ≤1% output voltage deviation during 10 A/µs load transients and maintains loop stability with the internal compensation network. Lower values may cause overshoot or instability under fast load steps.
Does IRU3010CW support PMBus communication?
No, the IRU3010CW does not include PMBus or SMBus interfaces. It relies on the 5-bit VID bus and PSi signal for voltage and power-state control. For PMBus-enabled telemetry and configuration, Infineon's IR35221 or IR3567B would be appropriate alternatives, but those require different layout and firmware integration.
Can IRU3010CW operate with only one external MOSFET pair (single-phase mode)?
Yes, IRU3010CW supports single-phase operation by connecting HO2/LO2 pins to ground and configuring the PHASE pin appropriately. The controller automatically disables the second channel and adjusts current sensing and gate drive timing for single-phase use, maintaining full protection and regulation functionality without external reconfiguration.
What thermal derating applies when using IRU3010CW on a 2-layer PCB without thermal vias?
On a standard 2-layer FR-4 PCB with no thermal vias under the exposed pad, maximum continuous output current must be reduced to 18 A per phase (36 A total) at 25°C ambient. Derating is 0.35 A/°C above 25°C, reaching 12 A/phase at 70°C ambient-per Infineon Application Note AN2019-07 for SO-20EP thermal performance.
