Output Voltage Requirements

2.9Overshoot at Turn-On or Turn-Off - REQUIRED

The core VRM/EVRD output voltage should remain within the load-line regulation band for the VID setting, while the VRM/EVRD is turning on or turning off, with no over or undershoot out of regulation. No negative voltage below –100 mV may be present at the VRM/EVRD output during turn-on or turn-off.

2.10Output Filter Capacitance - REQUIRED

The output filter capacitance for the VRM/EVRD11.0 based designs will be located on the baseboard. The system design must ensure that the output voltage of the VRM/ EVRD conforms to the load line of Figure 2-2and with the baseboard and processor loads. Table 2-7shows the number of decoupling caps recommended and other related specifications based on updated processor power requirements supported by VRM/ EVRD 11.0.

Figure 2-7through Figure 2-10are recommended examples of baseboard decoupling solutions and processor loads. Dual-Core Intel Xeon Processor-Based Server decoupling applies to all Dual-Core Intel Xeon Processor-Based Server/Dual-Core Intel® Xeon® Processor-Based Server/Dual-Core Intel Xeon Processor-Based Workstation platforms. The number of capacitors needed could change based on updated processor power requirements. The values shown are for a four to five phase 200 kHz to 700 kHz switching 150 A IccMAX/130 A IccTDC voltage regulator design with an output inductor range of 0.15 µH to 0.5 µH. The type and number of bulk decoupling required is dependent on the voltage regulator design and it is highly recommended that the OEM work with the VR supplier for an optimal decoupling solution for their system and in accordance to the processor’s design requirements.
