Antminer S19j Pro hash board troubleshooting for 20V boost circuit
-
The 20V boost circuit of the S19j Pro 42601 hash board is mainly to boost the 15V input voltage of the power supply to 20V, and then supply it to the LDO chips of the last 7 domains of the hash board. Of course, whether the circuit has a 20V output is also affected by whether the PIC chip works normally. Note that when we measure the voltage of this circuit, we measure it across capacitor C69. When checking the 20V boost circuit, we need to check whether each component here is abnormal.
