Infineon XDPE12284C0000XUMA1

The XDPE12284 is a digital dual rail 8 phase controller that provides power for Intel™ VR13, VR13HC, IMVP8 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. Command and monitor functions are controlled through the SVID interface which supports dynamic voltage identification (DVID) with 5 mV/step or 10 mV/step, power states (PS), VR Data and Operating Registers requirements. The XDPE12284 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 loadline accuracy over temperature. XDPE12284 also supports integrated power stages that provides integrated current sense and integrated temperature sense information. Protection features include a set of sophisticated over-voltage, under-voltage, over-temperature, and overcurrent protections. These attributes provide a complete and advanced protection feature set for microprocessor and power systems.
