Antminer D7 hashboard DC control circuit troubleshooting

The DC control circuit of the Antminer D7 hash board needs to work with the 23V boost circuit at the same time to control the conduction of the MOS chip, and the input voltage 13V is supplied to 35 voltage domains. And if the output voltage of the PIC chip is abnormal, this circuit will not work properly. This lesson will explain the circuit design of a DC control circuit and demonstrate how to measure it.
