The module operates from a 40V to 60V DC 24primary bus and provides a 12V regulated output voltage. It can deliver 25up to 860W continuous and 1300W in transient. 26 27The module has slow OCP and fast OCP. If the module output current is higher 28than slow OCP set point and the lasting time is also longer than the delay, 29the module will shut down and retry 3 time, if the fault still exists then 30module enter latch mode. 31 32If the module output current is higher than fast OCP set point then it shut 33down and enter latch mode. 34 35The driver is a client driver to the core PMBus driver. 36Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers. 37 38 39Usage Notes 40----------- 41 42This driver does not auto-detect devices. You will have to instantiate the 43devices explicitly.
