VCU1525 Board Power System
The VCU1525 board hosts a Linear Technology based power system. Essential input power
rails are sourced from the 16-lane PCIe connector CN1 through pins A2, A3, B1, and B2
12V_IN (12V), A9, A10, and B8 3V3_PEX_IN (3.3V) and B10 3V3AUX (3.3V).
The V
CCINT
voltage regulator has a PMBus interface. Figure 3-18 shows the VCU1525 power
system block diagram.
