Because the power supply of the ZYNQ FPGA has the power-on

sequence requirements, in the circuit design, we have designed according to

the

power

requirements

+1.0V->+1.8V->(+1.5 V, +3.3V, VCCIO) circuit design to ensure the normal

operation of the chip.

Part 20: Fan

Because ZYNQ035 generates a lot of heat when it works normally, we add

a heat sink and fan to the chip on the board to prevent the chip from

overheating. The control of the fan is controlled by the ZYNQ chip. The control

pin is connected to the IO of the BANK34. If the IO level output is low, the

MOSFET is turned on and the fan is working. If the IO level output is high, the

fan stops. The fan design on the board is shown in Figure 20-1.

The fan has been screwed to the AX7350B FPGA development board

before leaving the factory. The power of the fan is connected to the socket of
