描述
The XDP™ XDPE15284D is a hyper transient phase controller. Core voltage is provided by a multiphase buck converter with up to 8 synchronous-rectified channels in parallel while, a second loop provides voltage for the I/O. The XDPE15284D 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 8+0, 7+1, 6+2, 5+3, or 4+4 phases are supported.

Description

The XDPE15284 digital dual loop 8 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 8 synchronous-rectified channels in parallel while a second loop provides voltage for the I/O. The

XDPE15284 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 8+0, 7+1, 6+2, 5+3 or 4+4 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 uV and accuracy better than 0.5%.

The XDPE15284 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 XDPE15284 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 XDPE15284 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.

Infineon strongly recommends pairing Infineon’s powerstages with our Digital XDP™ family of controllers to ensure

correct interoperability. Interoperability when pairing with other vendor power stages/ discrete power

components cannot be guaranteed by Infineon and requires thorough evaluation and characterization by the

power stage/ discrete power component vendor.
