These are Step-Down Switching Regulator with PMBus Interface. 42 43MAX20830, and MAX20830C are 2.7V to 16V, 30A fully integrated step-down DC-DC 44switching regulators. MAX20840C is similar but can reach 40A. Through the PMBus 45interface, these devices can monitor input/output voltages, output current and 46temperature. 47 48The driver is a client driver to the core PMBus driver. Please see 49Documentation/hwmon/pmbus.rst for details on PMBus client drivers. 50 51Sysfs entries 52------------- 53 54================= ======================================== 55in1_label "vin" 56in1_input Measured input voltage 57in1_alarm Input voltage alarm 58in2_label "vout1" 59in2_input Measured output voltage 60in2_alarm Output voltage alarm 61curr1_label "iout1" 62curr1_input Measured output current 63curr1_alarm Output current alarm 64temp1_input Measured temperature 65temp1_alarm Chip temperature alarm 66================= ======================================== 67
