Product details
Overview
IR3567AMGB07TRP from Infineon Technologies (formerly International Rectifier) is a dual-output, 6+2-phase digital PWM controller for CPU voltage regulation, compliant with AMD SVI1/SVI2 and Intel VR12 specifications, featuring 200kHz–2MHz per-phase switching, IR Adaptive Transient Algorithm (ATA), and dual-loop OVP/UVP/OCP/OTP/CFP protection.
For engineers reviewing the IR3567AMGB07TRP datasheet, IR3567AMGB07TRP pinout, IR3567AMGB07TRP application, or IR3567AMGB07TRP equivalent, key selection criteria include SVI2/VR12 protocol support, dynamic phase control down to 1-phase + diode emulation, I²C/SMBus/PMBus telemetry, MTP configuration storage, and 7×7 mm QFN-56 package layout efficiency.
Technical Context
The IR3567A implements two independent digital control loops with proprietary non-linear PWM algorithms enabling IR's Adaptive Transient Algorithm (ATA) for minimized bulk capacitance. Each loop supports programmable phase count (1–6), automatic phase add/drop, and active diode emulation at light loads.
It integrates dual SVI2/VR12-compliant serial interfaces with full telemetry (voltage, current, temperature, power), thermistor-based thermal sensing with VRHOT/ICRIT# outputs, and Multiple Time Programmable (MTP) memory for customer-specific configurations without external EEPROM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output digital multi-phase controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IR3567BMGB07TRP | Same pinout and feature set; updated MTP firmware revision with enhanced CFP detection latency (≤150 ns vs. ≤200 ns) | Required for new designs targeting latest AMD SVI2.1 timing compliance | Select if designing for post-2018 AMD platforms requiring tighter fault response windows |
| MP8765GL-Z | Single-loop 8-phase controller; no dual-output or SVI2 support; uses proprietary I²C register map | Limited to monolithic CPU VR; lacks independent GPU/SoC rail control | Consider only for cost-sensitive single-rail applications where SVI2/VR12 is not required |

FAQ
What communication protocols does the IR3567AMGB07TRP support?
The IR3567AMGB07TRP supports I²C, SMBus, and PMBus protocols via dedicated SM_CLK and SM_DIO pins. It implements full PMBus v1.2 command sets for voltage/current/temperature/power telemetry, configuration, and fault logging-enabling seamless integration with system management controllers without protocol translation hardware.
Does the IR3567AMGB07TRP require external configuration memory?
No. The device integrates Multiple Time Programmable (MTP) non-volatile memory with an on-chip charge pump, storing all configuration parameters-including phase mapping, protection thresholds, and telemetry scaling factors-eliminating the need for external EEPROM or flash memory and reducing BOM cost and board area.
How does the IR3567AMGB07TRP handle thermal protection for dual outputs?
It provides independent thermal monitoring per loop using integrated thermistor inputs (TSEN1, TSEN2/VAUXSEN) and generates VRHOT_ICRIT# and VRHOT# signals with configurable trip points. These outputs can trigger independent throttling or shutdown of CPU or GPU domains without affecting the other rail, ensuring system-level thermal safety in heterogeneous workloads.
Can the IR3567AMGB07TRP operate with only one active output loop?
Yes. The controller supports independent enable/disable of each loop via EN and PWROK/EN_L2 pins. Loop 2 can be disabled while Loop 1 operates in full 6-phase mode, or both loops can run simultaneously in 6+2 configuration-enabling flexible use in single-CPU or CPU+GPU platforms without hardware modification.
