Vcore power regulation for Intel® VR13 rev1.1 and VR12.5
Rev1.5 based Microprocessors
Enterprise Line Description
The Infineon Technologies enterprise digital controllers
provide power for Intel® VR13 and VR12.5 applications.
Command and monitor functions are controlled through
the SVID interface which supports 5mV/step and
10mV/step VID tables, dynamic voltage identification
(DVID), power states (PS), and VR Data & Configuration
Register requirements.
Servers, Workstations, and High-end desktops
Enterprise Line Features
Compliant to Intel® VR13 and VR12.5 DC-DC converter
specifications
Compliant to Intel® SVID protocol rev1.7
Output voltage regulation range
0.5V to 2.5V (10mV/step)
0.25V to 1.52V (5mV/step)
Programmable to support one, two, or three fully digitally
controlled voltage rails
Advanced control loop features, such as Active Transient
Response (ATR) modulation and fast DVID response
enable optimal response to high di/dt load transients and
large voltage steps.
Programmable temperature compensation to current
sense allows the designer to tailor the response for best
loadline accuracy over temperature. Best in class noise
immunity is achieved through high oversample rate and
digital current estimation. Along with inductor DCR
current sensing, enterprise controllers also support
Infineon integrated power stages with integrated current
sense and integrated temperature sense. Enterprise
controllers support either ΔVBE or PTAT temperature
sensors which provide accurate loadline performance.

Configurable autonomous phase add/drop
Digitally programmable PID loop compensation
Digitally programmable loadline slope and offset
Digital temperature compensation
Input (+12V) power estimation
Extensive fault detection and protection capability
IUVP, IOVP, OUVP, OOVP (fixed and tracking)
OCP instantaneous, averaged (total current), channel, and
pulse-to-pulse current limit protection
Multiple internal and external OTP thresholds
Open/short voltage sense line detection
Negative current limit protection
Internal non-volatile memory (NVM) for custom configurations
Combined state-machine and µ-controller core architecture for
maximum flexibility
Protection features include a comprehensive suite of
sophisticated over-voltage, under-voltage, over-
temperature, and over-current protections. Enterprise
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.
