XDPE19284C
Description
The XDPE19284 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.
