Description
|
|
-----------
|
|
|
|
E50SN12051 is a 600W non-isolated 1/8th brick DC-DC power module.
|
|
|
|
This driver supports the E50SN12051 PMBus compliant monitor device.
|
|
|
|
The device provides measurements for:
|
|
|
|
* Input voltage
|
|
* Output current
|
|
* Output voltage
|
|
* Temperature
|
|
|
|
The driver is based on the PMBus core and exposes standard hwmon
|
|
sysfs attributes.
