Board Power Supply
This section describes the Arria 10 GX FPGA development board’s power supply. A laptop style DC
power supply is provided with the development kit. Use only the supplied power supply. The power
supply has an auto sensing input voltage range of 100 ~ 240 VAC and will output 12 VDC power at 16 A
to the development board. The 12 VDC input power is then stepped down to various power rails used by
the board components.
An on-board multi-channel analog-to-digital converter (ADC) measures both the voltage and current for
several specific board rails. The power utilization is displayed on a graphical user interface (GUI) that can
graph power consumption versus time.
Power Distribution System
The following figure below shows the power distribution system on the A10 FPGA development board.
Regulator efficiencies and sharing are reflected in the currents shown, which are at conservative absolute
maximum levels.
