Digital Dual Output 6+1 VR12.5 & VR13 CPU Controller
The Infineon Technologies enterprise digital controllers provide intelligent power for Intel™ VR12.5 and VR13 applications. Command and monitor functions are controlled through the Intel SVID interface which supports 5mV/step VID table, power states (PS), and VR Data & Configuration Register requirements. Infineon’s memory controllers utilize 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 load transients. Programmable temperature compensation to current sense allows the designer to tailor the response for best load line accuracy over temperature. Best-in-class noise immunity is achieved through high oversample rate and digital current estimation.
Protection features include a comprehensive suite of sophisticated over-voltage, under-voltage, over-temperature, and over-current protections. Memory controllers also detect and protect against an open or short circuit on the remote sensing inputs. These attributes provide a complete and advanced protection feature set for microprocessor and power systems.
