XDPE152C4D0000XUMA1

XDPE152C4D0000XUMA1 is an XDP™ 12-phase hyper transient phase dual loop multiphase controller. it provides power for Intel™ VR13, VR13HC, VR14 server, workstations, 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. Potential application includes Vcore power regulation for Intel™ VR13, VR13HC, VR14-based microprocessors, servers, workstations, high-end desktops, high Current ASIC, and PMBus POLs.
