| Description |
| ----------- |
| |
| The LX1308 is a high-efficiency, non-isolated, regulated 12V, 860W, |
| digital DC/DC power module. The module operates from a 40V to 60V DC |
| primary bus and provides a 12V regulated output voltage. It can deliver |
| up to 860W continuous and 1300W in transient. |
| |
| The module has slow OCP and fast OCP. If the module output current is higher |
| than slow OCP set point and the lasting time is also longer than the delay, |
| the module will shut down and retry 3 time, if the fault still exists then |
| module enter latch mode. |
| |
| If the module output current is higher than fast OCP set point then it shut |
| down and enter latch mode. |
| |
| The driver is a client driver to the core PMBus driver. |
| Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers. |
| |
| |
| Usage Notes |
| ----------- |
| |
| This driver does not auto-detect devices. You will have to instantiate the |
| devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for |
| details. |
