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. The IR3565A provides extensive OVP, UVP, OCP and OTP fault protection and includes thermistor based temperature sensing with VRHOT signal. 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. • SVI1 & SVI2, VR12 based systems • Desktop & Notebook CPU VRs • High Performance Graphics Processors ORDERING INFORMATION Base Part Number IR3565A Package Type QFN 6 mm x 6 mm Standard Pack Form Quantity Tape and Reel 3000 Orderable Part Number IR3565AMxxyyTRP1 IR3565A QFN 6 mm x 6 mm Tape and Reel 3000 IR3565AMTRPBF IR3565A QFN 6 mm x 6 mm Tray 4900 IR3565AMTYPBF Notes 1 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 IR3565A ORDERING INFORMATION IR3565AM P/PBF Lead Free TR Tape & Reel / TY - Tray yy Configuration File ID xx Customer ID Package Type QFN IRTN1 ISEN1 IRTN2 ISEN2 IRTN3 ISEN3 IRTN4 ISEN4 IRTN2_L2 ISEN2_L2 IRTN1_L2 ISEN1_L2 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 8 IR3565A 48 Pin 6x6 QFN Top View 32 VRTN_L2 31 PWM1_L2 30 PWM2_L2 29 PWM4 V18A 9 PWRGD/ VRDY1 10 PWROK/EN_L2/ INMODE VINSEN 12 13 14 15 16 28 PWM3 27 PWM2 49 GND 26 PWM1 VGD/TSEN2/ VAUXSEN 17 18 19 20 21 22 23 24 NC VIDDIO/ SV_ADDR SVT/ SV_ALERT SV_CLK/ VIDSEL1 SV_DIO/ VIDSEL0 VRHOT_ICRIT EN ADDR_PRO T SM_ALERT SM_DIO SM_CLK Figure 1 IR3565A Pin Diagram Enlarged 2 \| 2013 International Rectifier \| Product Brief \| October 1, 2013 \| V3.04 Dual Output Digital Multi-Phase Controller IR3565A TYPICAL APPLICATION DIAGRAM R series R series
