XDPE12284C0000XUMA1

XDPE12284C0000XUMA1 is a digital multi-phase controller. It is an 8-phase dual-loop voltage regulator. Command and monitor functions are controlled through the SVID interface which supports dynamic voltage identification (DVID) with 5 V/step or 10mV/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. Potential applications are core and memory power regulation for Intel™ VR13, VR13HC, IMVP8 and IMVP9 based microprocessors (servers, workstations, high-end desktops).

• Compliant with Intel™ SVID rev 1.9.1 protocol
• Output voltage regulation range from 0.2V to 3.04V
• Configurable autonomous phase add/drop, automatic phase detection at start-up
• Start-up into pre-bias voltage at the output, integrated power stage current sense
• Differential output voltage sense, digital current balancing
• Digitally programmable PID (proportional, integral, differential) loop compensation
• Internal non-volatile memory (NVM) to store multiple custom configurations
• Digital temperature compensation, input (+12V) voltage and current sense
• Flexible phase assignment between the two loops: 8+0, 7+1, 6+2, …, 4+4 phases
• PG-VQFN-40 package
