ARTIX-7 FPGA Development Board AX7A200 User Manual
Figure 2-10-1：Power Supply on core board schematic
The core board is powered by +5V and converted to +3.3V, +1.5V, +1.8V,
+1.0V four-way power supply through three DC/DC power supply chip
TLV62130RGT. The current of +1.0V can be up to 6A, and the other three
output currents can be up to 3A. The VCCIO is generated by one
LDOSPX3819M5-3-3. VCCIO mainly supplies power to BANK15 and BANK16
of FPGA. Users can change the IO of BANK15,16 to different voltage
standards by replacing their LDO chip. The 1.5V generates the VTT and VREF
voltages required by DDR3 via TI's TPS51200. The 1.8V power supply of
MGTAVTT and MGTAVCC for the GTP transceiver is generated by TI's
TPS74801 chip. The functions of each power distribution are shown in the
following table:
