Dual Output Digital Multi-Phase Controller IR3566A • Dual output 6+1 phase PWM Controller • Fully supports SVI1 & SVI2 with dual OCP and VR12 • PVI and SVI GPU VR modes • Overclocking & Gaming Mode • Switching frequency from 200kHz to 2MHz per phase • IR Efficiency Shaping Features including Dynamic Phase Control and Automatic Power State Switching • Programmable 1-phase operation for Light Loads and Active Diode Emulation for Very Light Loads • IR Adaptive Transient Algorithm ATA on both loops minimizes output bulk capacitors and system cost • Auto-Phase Detection with auto-compensation • Per-Loop Fault Protection OVP, UVP, OCP, OTP • I2C/SMBus/PMBus system interface for telemetry of Temperature, Voltage, Current & Power for both loops • Multiple Time Programming MTP with integrated charge pump for easy custom configuration • Compatible with IR ATL and 3.3V tri-state Drivers • +3.3V supply voltage -40°C to 85°C ambient operation • Pb-Free, RoHS, 6x6mm, 48-pin, 0.4mm pitch QFN The IR3566A is a dual-loop digital multi-phase buck controller designed for CPU voltage regulation and is fully compliant with SVI1 & SVI2 and Intel VR12 specifications. The IR3566A includes IR’s Efficiency Shaping Technology to deliver exceptional efficiency at minimum cost across the entire load range. IR Variable Gate Drive optimizes the MOSFET gate drive voltage based on real-time load current. IR’s Dynamic Phase Control adds/drops active phases based upon load current and can be configured to enter 1-phase operation and diode emulation mode automatically or by command. IR’s unique Adaptive Transient Algorithm ATA , based on proprietary non-linear digital PWM algorithms, minimizes output bulk capacitors and Multiple Time Programmable MTP storage saves pins and enables a small package size. Device configuration and fault parameters are easily defined using the IR Digital Power Design Center DPDC GUI and stored in onchip MTP. The IR3566A provides extensive OVP, UVP, OCP and OTP fault protection and includes thermistor based temperature sensing with VRHOT signal. The IR3566A includes numerous features like register diagnostics for fast design cycles and platform differentiation, simplifying VRD design and enabling fastest time-to-market TTM with “set-and-forget” methodology. • SVI1 & SVI2, VR12 based systems • Servers and High End Desktop CPU VRs • High Performance Graphics Processor ORDERING INFORMATION Base Part Number IR3566A Package Type QFN 6 mm x 6 mm Standard Pack Form Quantity Tape and Reel 3000 Orderable Part Number IR3566AMxxyyTRP1 IR3566A QFN 6 mm x 6 mm Tape and Reel 3000 IR3566AMTRPBF IR3566A QFN 6 mm x 6 mm Tray 4900 IR3566AMTYPBF Notes Customer Specific Configuration File, where xx = Customer ID and yy = Configuration File Codes assigned by IR Marketing . 1 \| 2013 International Rectifier \| Product Brief \| October 1, 2013 \| V3.04 Dual Output Digital Multi-Phase Controller IR3566A ORDERING INFORMATION IR3566AM P/PBF Lead Free TR Tape & Reel / TY - Tray yy Configuration File ID xx Customer ID Package Type QFN IRTN6 IRTN1 ISEN1 IRTN2 ISEN2 IRTN3 ISEN3 IRTN4 ISEN4 IRTN5 ISEN5 IRTN1_L2 48 47 46 45 44 43 42 41 40 39 38 37 ISEN6 1 RCSP 2 36 ISEN1_L2 35 RCSP_L2 RCSM 3 VRDY2 4 VSEN 5 VRTN 6 RRES 7 TSEN1 8 V18A 9 VRDY1 10 EN_L2/INMODE/PWROK 11 VINSEN 12 34 RCSM_L2 33 VCC IR3566A 48 Pin 6 x 6 QFN Top View 32 VSEN_L2 31 VRTN_L2 30 PWM1_L2 29 PWM6 28 PWM5 27 PWM4 49 GND 26 PWM3 25 PWM2 13 14 15 16 17 18 19 20 21 22 23 24 SV_ADDR/VDDIO SV_ALERT#/SVT SV_CLK/ VIDSEL1 SV_DIO/ VIDSEL0 VRHOT_CRIT# EN ADDR_PROT SM_ALERT# SM_DIO SM_CLK VGD/TSEN2/ VAUXSEN PWM1 Figure 1 IR3566A Pin Diagram Enlarged 2 \| 2013 International Rectifier \| Product Brief \| October 1, 2013 \| V3.04 Dual Output Digital Multi-Phase Controller IR3566A TYPICAL APPLICATION DIAGRAM R series RCSP R series RCSM +3.3V PWM1 ISEN1 IRTN1 IR3566A VSEN VRTN RRES TSEN1 RTh 2 PWM2 ISEN2 IRTN2 +12V Main R VIN_ 1 RVIN _2
