Single Output Digital Multi-Phase Controller IR3563B FEATURES DESCRIPTION 8-phase single output PWM Controller The IR3563B is a single-loop digital multi-phase buck controller that controls up to 8 phases. The Intel VR12 and VR12.5 modes & Memory VR IR3563B is fully Intel VR12 and VR12.5 compliant. mode Complies with VR12.5 Rev 1.3 requirement for SVID The IR3563B includes IRs Efficiency Shaping register 15h to have <200 Sec filter Technology to deliver exceptional efficiency at minimum cost across the entire load range. IR Overclocking & Gaming Mode Variable Gate Drive optimizes the MOSFET gate PVI and SVI GPU VR modes drive voltage based on real-time load current. IRs Switching frequency from 200kHz to 2MHz Dynamic Phase Control adds/drops phases based per phase upon load current. The IR3563B can be configured to enter 1-phase operation and active diode IR Efficiency Shaping Features including Variable emulation mode automatically or by command. Gate Drive, Dynamic Phase Control and Automatic Power State Switching IRs unique Adaptive Transient Algorithm (ATA), IR Adaptive Transient Algorithm (ATA) minimizes based on proprietary non-linear digital PWM output bulk capacitors and system cost algorithms, minimizes output bulk capacitors. Auto-Phase Detection with auto-compensation The I2C/PMBus interface can communicate with up Fault Protection: OVP, UVP, OCP, OTP, CFP to 16 IR3563B-based VR loops. Device configuration and fault parameters are easily defined I2C/SMBus/PMBus system interface for telemetry of Temperature, Voltage, Current & Power using the IR Digital Power Design Center (DPDC) GUI and stored in on-chip MTP. MTP storage saves Multiple Time Programming (MTP) with integrated pins and enables a small package size. charge pump for easy custom configuration Compatible with IR ATL and 3.3V tri-state Drivers The IR3563B provides extensive OVP, UVP, OCP and OTP fault protection and includes thermistor +3.3V supply voltage -40C to 85C ambient based temperature sensing with VRHOT signal. operation Pb-Free, RoHS, 6x6mm 48-pin, 0.4mm pitch QFN The IR3563B also includes numerous features like register diagnostics for fast design cycles and platform differentiation, simplifying VRD design and APPLICATIONS enabling fastest time-to-market with its set-and- Intel VR12 and VR12.5 based systems forget methodology.
