Dual Output Digital Multi-Phase Controller FEATURES IR3567B DESCRIPTION Dual output 6+2 phase PWM Controller The IR3567B is a dual-loop digital multi-phase buck controller designed for CPU voltage regulation and is fully compliant with AMD(R) SVI1 & SVI2 and Intel(c) VR12 & VR12.5 specifications. Easiest layout and fewest pins in the industry Fully supports AMD(R) SVI1 & SVI2 with dual OCP and Intel(R) VR12 & VR12.5 Complies with VR12.5 Rev 1.3 requirement for SVID register 15h to have <200 Sec filter Overclocking & Gaming Mode Switching frequency from 200kHz to 2MHz per phase IR Efficiency Shaping Features including Dynamic Phase Control and Automatic Power State Switching 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, CFP I2C/SMBus/PMBus system interface for telemetry of Temperature, Voltage, Current & Power for both loops The IR3567B 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 IR3567B 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 IR3567B 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.
