Dual Output Digital Multi-Phase Controller IR3567B FEATURES DESCRIPTION Dual output 6+2 phase PWM Controller The IR3567B is a dual-loop digital multi-phase buck controller designed for CPU voltage regulation and is Easiest layout and fewest pins in the industry fully compliant with AMD SVI1 & SVI2 and Intel Fully supports AMD SVI1 & SVI2 with dual VR12 & VR12.5 specifications. OCP and Intel VR12 & VR12.5 The IR3567B includes IRs Efficiency Shaping Complies with VR12.5 Rev 1.3 requirement for Technology to deliver exceptional efficiency at SVID register 15h to have <200 Sec filter minimum cost across the entire load range. IR Variable Overclocking & Gaming Mode Gate Drive optimizes the MOSFET gate drive voltage Switching frequency from 200kHz to 2MHz based on real-time load current. IRs Dynamic Phase per phase Control adds/drops active phases based upon load current and can be configured to enter 1-phase IR Efficiency Shaping Features including operation and diode emulation mode automatically or Dynamic Phase Control and Automatic Power by command. State Switching IR Adaptive Transient Algorithm (ATA) on both IRs unique Adaptive Transient Algorithm (ATA), based loops minimizes output bulk capacitors and on proprietary non-linear digital PWM algorithms, system cost minimizes output bulk capacitors and Multiple Time Auto-Phase Detection with auto-compensation Programmable (MTP) storage saves pins and enables a small package size. Device configuration and fault Per-Loop Fault Protection: OVP, UVP, OCP, parameters are easily defined using the IR Digital OTP, CFP Power Design Center (DPDC) GUI and stored in on- I2C/SMBus/PMBus system interface for chip MTP. telemetry of Temperature, Voltage, Current & Power for The IR3567B provides extensive OVP, UVP, OCP and both loops OTP fault protection and includes thermistor based temperature sensing with VRHOT signal. Multiple Time Programming (MTP) with integrated charge pump for easy custom The IR3567B includes numerous features like register configuration diagnostics for fast design cycles and platform Compatible with IR ATL and 3.3V tri-state differentiation, simplifying VRD design and enabling Drivers fastest time-to-market (TTM) with set-and-forget +3.3V supply voltage -40C to 85C ambient methodology. operation Pb-Free, RoHS, 7x7mm, 56-pin, 0.4mm pitch APPLICATIONS QFN AMD SVI1 & SVI2, Intel VR12 & VR12.5 based systems Desktop & Notebook CPU VRs High Performance Graphics Processors ORDERING INFORMATION Standard Pack Base Part Orderable Package Type Number Part Number Form Quantity 1 IR3567B QFN 7 mm x 7 mm Tape and Reel 3000 IR3567BMxxyyTRP IR3567B QFN 7 mm x 7 mm Tape and Reel 3000 IR3567BMTRPBF IR3567B QFN 7 mm x 7 mm Tray 2600 IR3567BMTYPBF Notes: 1.
