IR3564A IR3570A Dual Output Digital Multi-Phase Controller FEATURES DESCRIPTION  Dual output 4+1 and 3+2 phase PWM Controllers The IR3564A/70A 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  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 telemetryof 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 The IR3564A/70A includes IR’s Efficiency Shaping Technology to deliver exceptional efficiency at minimum cost across the entire load range. 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 IR3564A/70A provides extensive OVP, UVP, OCP and OTP fault protection and includes thermistor based temperature sensing with VRHOT signal. The IR3564A/70A 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.
