DESCRIPTION
TM
way to implement a complete AMD SVID or PVID power solution. It has the ability to independently control
both the VDD core and VDDNB auxiliary planes required by the CPU when operated in SVI (Serial VID
Interface) mode. The IR3514 can also receive Power Savings commands through the SVI serial bus and
communicate this information to the IR3507 or other Phase ICs with PSI input capabilities. When operated
in PVI (Parallel VID Interface) mode, the IR3514 controls the VDD core plane through 6 Parallel VID bits
and the VDDNB auxiliary plane power stage goes to high impedance. PVI/SVI selection is made by
sampling VID1 input upon Enable. The IR3514 interfaces with any number of Phase ICs each driving and

expensive, and easier to design while providing higher efficiency than conventional approaches.

In SVI Mode (VID1=0 upon Enable)
o 2 converter outputs for the AMD processor VDD core and VDDNB auxiliary planes
o AMD Serial VID interface independently programs both output voltages and operation
o Both converter outputs boot to 2- bit “Boot” VID codes which are read and stored from the SVC
& SVD parallel inputs upon the assertion of the Enable input
o PWROK input signal activates SVID after successful boot start-up
o Both converter outputs can be independently turned on and off through SVID commands
o Deassertion of PWROK prior to Enable causes the converter output to transition to the stored
Pre-PWROK VID codes
o Connecting the PWROK input to VCCL disables SVID and implements VFIX mode with both
output voltages programmed via SVC & SVD parallel inputs per the 2 bit VFIX VID codes
o PSI_L commands are forwarded to VDD core phase ICs
In PVI Mode (VID1=1 upon Enable)
o Single converter control for VDD with the VDDNB power stage in a high impedance state
o AMD 6 bit parallel VID programs the VDD regulation voltage
VRRDY monitors output voltages, VRRDY will deassert if any output voltage is out of spec
0.5% overall system set point accuracy
