Antminer L7 hash board troubleshooting about the 19V boost circuit
-
The L7 hash board has two boost circuits. This video mainly explains the 19V boost circuit. This circuit boosts the 15V input voltage of the power supply to 19V, and then supplies it to the LDO chips of the last 4 domains of the hash board. In addition, for the circuit to work normally, it needs to be controlled by the voltage output by the PIC chip. A voltage of about 19V can be measured at the filter capacitor of this circuit.
