XDPE14284A-0000
XDP™ 8-phase dual loop digital multiphase controller
The XDP™ XDPE14284A is a digital dual rail 8-phase controller that provides power for Intel VR13, VR13HC, VR14 and IMVP9 server, workstation, and high-end desktop applications. The controller offers flexible phase assignment between the two loops and can be configured in any of the following ways: 8+0, 7+1, 6+2, ... ,4+4.
The XDPE14284A 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 Active Transient Response (ATR) modulation and fast DVID response enable optimal response to high slew rate load transients. Programmable temperature compensation to current sense allows the designer to tailor the response for best load line accuracy over temperature. XDPE14284A also supports integrated power stages that provides integrated current sense and integrated temperature sense information.
