UltraPortableDigitalMultiPhaseMobileController IR3588 FEATURES DESCRIPTION Ultra Low Power single loop PWM Controller The IR3588 is a flexible single loop digital multi-phase with 2 PWMs configurable as 1, 2, or 4 phase buck controller that can be configured as a 1, 2 or 4 systems phase system when combined with the IR Dual 6x8mm Compliant with Intel VR12.5 Rev 1.3/VR12.6 IR3548 or 5x6mm IR3552. Rev1.0 specifications Power consumption is minimized while maintaining full Intel VR12.5 / VR12.6 SVID or I2C controlled regulation digital capability and flexibility. Digital non-linear transient control allows lower frequency operation to achieve the Optimized for 1 or 2 phase Ultrabook highest efficiency possible while providing minimal all solution when paired with IR3548 or IR3552 PowIRstage ceramic output capacitor solutions. The IR3588 includes IRs Efficiency Shaping Technology to automatically <1mW in PS4, <50mW Maximum deliver exceptional efficiency at minimum cost across the Performance entire load range and can be configured to enter 1-phase 48mV/s Dynamic VID capable for fast wake- operation and active diode emulation mode automatically up and regenerative braking or by command. The IR3588 may also shut down Dynamic Phase Control and Automatic Power connected drivers/PowIRstage to minimize the quiescent State Switching with Active Diode Emulation current consumption in the system. for Very Light Loads I2C system interface for telemetry of IRs unique Adaptive Transient Algorithm (ATA), based Temperature, Voltage, Input and Output on proprietary non-linear digital PWM algorithms, Current & Power minimizes output bulk capacitors, and improves transient Fault Protection: Output OVP, UVP, OC response and form factor. Warn, OCP, OT Warn, OTP Device configuration and fault parameters are easily IR Adaptive Transient Algorithm (ATA) minimizes output bulk capacitors and system defined using the IR Digital Power Design Center (DPDC) cost GUI and stored in on-chip MTP. MTP storage saves pins 8 Time Programming (MTP) with integrated and enables a small package size. Fault protection charge pump for easy custom configuration includes output OV, UV and OC protection, thermistor or Overclocking & Gaming Mode up to 2.3VOUT Diode based OT protection sensing with a VRHOT signal output and a Over Current warning flag. 200kHz to 2MHz switching frequency per phase APPLICATIONS +3.3V supply voltage -40C to 85C ambient operation High Performance Portable Pb-Free, RoHS, 4x4mm, 28-pin, 0.4mm pitch QFN Net/Note/Ultra Book ORDERING INFORMATION Standard Pack Base Part Orderable Package Type Programming Number Part Number Form Quantity IR3588 QFN 4 mm x 4 mm Tape and Reel 3000 IR3588MTRPBF Default 1 IR3588 QFN 4 mm x 4 mm Tape and Reel 3000 IR3588MxxyyTRP Customer Configuration Notes: 1.
