Infineon XDPE152C4D1000XUMA1

The XDPE152C4 digital dual loop 12 phase controller provides power for Intel™ VR13, VR13HC, VR14 server, workstation, and high - end desktop applications. Core voltage is provided by a multi - phase buck converter with up to 12 synchronous - rectified channels in parallel while a second loop provides voltage for the I/O. The XDPE152C4 phase configuration is flexible in how the phases are allocated to the 2 loops. Any phase can be assigned to either loop and the phase firing order is fully programmable to offer the ultimate in phase configuration flexibility. Typically, configurations of 12+0, 11+1, 10+2, 8+4 or 6+6 phases are supported. Command and monitoring functions are controlled through the PMBus and SVID interfaces which supports dynamic voltage identification with 5 mV/step or 10 mV/step in Intel mode, output range up to 3.04 V: offset and trim resolution of 625 μV and accuracy better than 0.5%. The XDPE152C4 controller utilizes digital technology to implement all control functions, providing the ultimate system solution in terms of flexibility and stability. Advanced control loop features, such as current mode control, variable frequency operation, Active Transient Response (ATR/FATR), fast DVID response, automatic phase shedding and Pulse Frequency Modulation (PFM) enable optimal response to a highly dynamic load with fast di/dt load transients across a wide range of load current. The XDPE152C4 controller supports multi - vendor pin compatible integrated power stages with trivalent PWM interfaces, fast response, integrated current sense, integrated temperature sense, and advanced fault detection capability, interface and signaling. In addition to supporting power stage fault protection features, the XDPE152C4 controller also includes a set of sophisticated over - voltage, under - voltage, over - temperature, over - current, and phase fault protections. These attributes provide a complete and advanced protection feature set for microprocessor and power systems.
