IR3564A Dual Output Digital Multi-Phase Controller IR3570A FEATURES DESCRIPTION Dual output 4+1 and 3+2 phase PWM The IR3564A/70A is a dual-loop digital multi-phase buck Controllers controller designed for CPU voltage regulation and is fully compliant with AMD SVI1 & SVI2 and Intel VR12 Easiest layout and fewest pins in the industry specifications. Fully supports AMD SVI1 & SVI2 with dual OCP and Intel VR12 The IR3564A/70A includes IRs Efficiency Shaping Technology to deliver exceptional efficiency at minimum Overclocking & Gaming Mode cost across the entire load range. IRs Dynamic Phase Switching frequency from 200kHz to 2MHz Control adds/drops active phases based upon load per phase current and can be configured to enter 1-phase operation IR Efficiency Shaping Features including and diode emulation mode automatically or by command. Dynamic Phase Control and Automatic Power State Switching IRs unique Adaptive Transient Algorithm (ATA), based on proprietary non-linear digital PWM algorithms, Programmable 1-phase operation for Light minimizes output bulk capacitors and Multiple Time Loads and Active Diode Emulation for Very Programmable (MTP) storage saves pins and enables a Light Loads small package size. Device configuration and fault IR Adaptive Transient Algorithm (ATA) on parameters are easily defined using the IR Digital Power both loops minimizes output bulk capacitors Design Center (DPDC) GUI and stored in on-chip MTP. and system cost Auto-Phase Detection with auto- The IR3564A/70A provides extensive OVP, UVP, OCP compensation and OTP fault protection and includes thermistor based temperature sensing with VRHOT signal. Per-Loop Fault Protection: OVP, UVP, OCP, OTP, CFP The IR3564A/70A includes numerous features like I2C/SMBus/PMBus system interface for register diagnostics for fast design cycles and platform telemetryof Temperature, Voltage, Current & differentiation, simplifying VRD design and enabling Power for both loops fastest time-to-market (TTM) with set-and-forget methodology. Multiple Time Programming (MTP) with integrated charge pump for easy custom configuration APPLICATIONS Compatible with IR ATL and 3.3V tri-state AMD SVI1 & SVI2, Intel VR12 based systems Drivers Desktop & Notebook CPU VRs +3.3V supply voltage -40C to 85C ambient operation GPU & Memory VRs Pb-Free, RoHS, 5x5mm, 40-pin, 0.4mm pitch QFN ORDERING INFORMATION Standard Pack Base Part Orderable Package Type Number Part Number Form Quantity 1 IR3564A IR3564AMxxyyTRP QFN 5 mm x 5 mm Tape and Reel 3000 1 IR3570A R3570AMxxyyTRP IR3564A IR3564AMTRPBF QFN 5 mm x 5 mm Tape and Reel 3000 IR3570A IR3570AMTRPBF IR3564A IR3564AMTYPBF QFN 5 mm x 5 mm Tray 4900 IR3570A IR3570AMTYPBF 1.
