2.2.1 QM_XC7A35T_SDRAM 3.3V Power Supply
The core board’s 3.3V power supply is using high efficiency DC/DC chip MP2359 provided by MPS Inc. The
MP2359 supports wide voltage input range from 4.5V to 24V. In normal use case, 5V DC power supply is
suggested to be applied on the board. Below image shows the MP2359 hardware design:
