Dual Output Digital Multi-Phase Controller FEATURES IR3565A DESCRIPTION  Dual output 4+2 phase PWM Controller The IR3565A is a dual-loop digital multi-phase buck controller designed for CPU voltage regulation and is fully © compliant with AMD® SVI1 & SVI2 and Intel VR12 specifications.  Easiest layout and fewest pins in the industry  Fully supports AMD® SVI1 & SVI2 with dual OCP and Intel® VR12  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 The IR3565A 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 realtime 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 on-chip MTP.  IR Adaptive Transient Algorithm (ATA) on both loops minimizes output bulk capacitors and system cost  Auto-Phase Detection with autocompensation  Per-Loop Fault Protection: OVP, UVP, OCP, OTP, CFP  I2C/SMBus/PMBus system interface for telemetry of Temperature, Voltage, Current & Power for both loops The IR3565A provides extensive OVP, UVP, OCP and OTP fault protection and includes thermistor based temperature sensing with VRHOT signal.  Multiple Time Programming (MTP) with integrated charge pump for easy custom configuration The IR3565A 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.  Compatible with IR ATL and 3.3V tri-state Drivers APPLICATIONS  +3.3V supply voltage; -40°C to 85°C ambient operation  AMD® SVI1 & SVI2, Intel® VR12 based systems  Pb-Free, RoHS, 6x6mm, 48-pin, 0.4mm pitch QFN  High Performance Graphics Processors  Desktop & Notebook CPU VRs ORDERING INFORMATION Base Part Number Package Type IR3565A Standard Pack Form Quantity Orderable Part Number QFN 6 mm x 6 mm Tape and Reel 3000 IR3565AMxxyyTRP IR3565A QFN 6 mm x 6 mm Tape and Reel 3000 IR3565AMTRPBF IR3565A QFN 6 mm x 6 mm Tray 4900 IR3565AMTYPBF 1 Notes 1: Customer Specific Configuration File, where xx = Customer ID and yy = Configuration File (Codes assigned by IR Marketing). 1 www.irf.com | © 2013 International Rectifier | Product Brief | October 1, 2013 | V3.04 Dual Output Digital Multi-Phase Controller IR3565A ORDERING INFORMATION IR3565AM          P/PBF – Lead Free TR – Tape & Reel / TY - Tray yy – Configuration File ID xx – Customer ID IRTN1 ISEN1 IRTN2 ISEN2 IRTN3 ISEN3 IRTN4 ISEN4 IRTN2_L2 ISEN2_L2 IRTN1_L2 ISEN1_L2 Package Type (QFN) 48 47 46 45 44 43 42 41 40 39 38 37 RCSP 1 36 RCSP_L2 RCSM 2 35 RCSM_L2 VRDY2 3 34 VCC CFP 4 33 VSEN_L2 VSEN 5 VRTN 6 RRES 7 TSEN1 V18A PWRGD/ VRDY1 PWROK/EN_L2/ INMODE 32 VRTN_L2 31 PWM1_L2 30 PWM2_L2 8 29 PWM4 9 28 PWM3 10 27 PWM2 11 26 PWM1 25 VGD/TSEN2/ VAUXSEN IR3565A 48 Pin 6x6 QFN Top View 49 GND 19 20 21 22 23 24 SM_CLK NC 18 SM_DIO 17 SM_ALERT 16 EN 15 VRHOT_ICRIT 14 VIDDIO/ SV_ADDR SVT/ SV_ALERT SV_CLK/ VIDSEL1 SV_DIO/ VIDSEL0 NC 13 ADDR_PRO T VINSEN 12 Figure 1: IR3565A Pin Diagram Enlarged 2 www.irf.com | © 2013 International Rectifier | Product Brief | October 1, 2013 | V3.04 Dual Output Digital Multi-Phase Controller IR3565A 5V V TYPICAL APPLICATION DIAGRAM 12V Boot Vcc RCSP R series Vdrv CHL8505 HiGate Switch V_CPU_L1 CCS RCS RCSM +3.3V PWM GND LoGate Boot Vcc CHL8505 HiGate Switch L O A D PWM1 ISEN1 IRTN1 R series VCC 5V V RTh IR3565A 12V Vdrv VSEN PWM GND VRTN LoGate RRES TSEN1 5V V PWM2 ISEN2 IRTN2 12V RTh 2 Boot Vcc Vdrv V18A PWM GND LoGate PWM3 ISEN3 TSEN2 12V CHL8505 HiGate Switch IRTN3 RTh 3 VINSEN VRDY1 R VIN _ 2 5V V R VIN _ 1 VRDY2 Vdrv V V EN PWROK/EN_L2/INMODE VDDIO 5V 12V Boot Vcc VDDIO/SV_ADDR Vdrv PWM GND Applicable circuit when pin is configured as VDDIO only V_CPU_L2 L O A D LoGate ISEN1_L2 IRTN1_L2 5V V V V SM_DIO SM_CLK SM_ALERT# 12V RCSP_L2 R series Boot Vcc CCS RCS RTh CHL8505 HiGate Switch PWM1_L2 V I2C Bus LoGate ISEN4 IRTN4 VRHOT_CRIT# From System PWM GND PWM4 CHL8505 HiGate Switch V V SVT/SV_ALERT SV_DIO SV_CLK V CPU Serial Bus 12V Boot Vcc Vdrv R series RCSM_L2 PWM2_L2 VSEN_L2 ISEN2_L2 IRTN2_L2 PWM GND CHL8505 HiGate Switch LoGate VRTN_L2 ADDR_PROT GND Figure 2: Dual-loop VR using IR3565A Controller and CHL8505 MOSFET Drivers in 4+2 Configuration 3 www.irf.com | © 2013 International Rectifier | Product Brief | October 1, 2013 | V3.04 Dual Output Digital Multi-Phase Controller IR3565A Data and specifications subject to change without notice.
