Antminer S19XP hashboard about the LDO powering knowledge

LDO powering is one of the core power supplies for the ASIC chip on the Antminer S19xp hash board. Each group of domains will correspond to one LDO1.2V and one PPL0.8V. Only when all LDO chips provide normal powering can one of the conditions for the normal operation of ASIC chips be met. Similarly, this hash board has two LDO powering methods. The LDO powering for domains 1-9 is divided by the domain voltage in series, and the last 2 domains are powered by the output voltage of the boost circuit. Watch the video to learn and master their different ways of powering.
