The 17V boost circuit of Whatsminer M32 hash board is composed of a boost chip, a boost inductor, a rectifier diode and 2 filter capacitors. Its function is to convert the 13V output from the power supply 17V, and then supply it to the LDO chips of the last 9 domains for use. If there is an anomaly here, then the last 9 months LDO chip on the M32 hash board is not working properly.
