Description
|
|
-----------
|
|
|
|
This driver supports hardware monitoring for Analog Devices MAX20830
|
|
Step-Down Switching Regulator with PMBus Interface.
|
|
|
|
The MAX20830 is a 2.7V to 16V, 30A fully integrated step-down DC-DC switching
|
|
regulator. Through the PMBus interface, the device can monitor input/output
|
|
voltages, output current and temperature.
|
|
|
|
The driver is a client driver to the core PMBus driver. Please see
|
|
Documentation/hwmon/pmbus.rst for details on PMBus client drivers.
