5.4.1.2
Figure 5-18
The board receives IPMCV (3.3 V), 12 V, and ground from the AdvancedMC edge connector. The 12 V
is fed to three DC-DC power modules. Two Power-One modules separately generate the 1.1 V core and
3.3 V IO supply voltages. The TPS51116 voltage regulator is designed exclusively for use with the DDRII
memory. This device generates the power and reference supply for the two DDR2 SoCDIMMs. Two
Maxim MAX8526 devices are used to generate additional 2.5 V and 1.2 V board power supplies. A single
Micrel MIC5205 device is used to provide the 5 V power supply for the TPS51116 device and the
FT2232D dual USB controller, generated from the 12 V AdvancedMC supply.
5.4.1.3
The Power-One voltage regulators have user selectable output voltages defined using trim resistors. The
following equation is used to calculate the correct output voltage.
Using this equation, a trim resistor value of 29.2 kΩ is required on the Power-One YNC12S20 device
(1.1-V voltage regulator). (As this is not a standard resistor value, two parallel resistors (43 kΩ//91 kΩ)
