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.
