MFR_READ_IIN
The MFR_READ_IIN command is a paged reading of the input current that applies the paged MFR_IIN_OFFSET
parameter. This calculation is similar to READ_IIN except the paged values are used.
MFR_READ_IIN = MFR_IIN_OFFSET + (IOUT • DUT
YCYCLE)
This command has 2 data bytes and is formatted in Linear_5s_11s format.
READ_IOUT
The READ_IOUT command returns the average output current in amperes. The IOUT value is a function of:
a) the differential voltage measured across the I
SENSE
pins
b) the IOUT_CAL_GAIN value
c) the MFR_IOUT_CAL_GAIN_TC value, and
d) READ_TEMPERATURE_1 value
e) The MFR_TEMP_1_GAIN and the MFR_TEMP_1_OFFSET
This read-only command has two data bytes and is formatted in Linear_5s_11s format.
READ_TEMPERATURE_1
The READ_TEMPERATURE_1 command returns the temperature, in degrees Celsius, of the external sense element.
This read-only command has two data bytes and is formatted in Linear_5s_11s format.
READ_TEMPERATURE_2
The READ_TEMPERATURE_2 command returns the temperature, in degrees Celsius, of the internal sense element.
This read-only command has two data bytes and is formatted in Linear_5s_11s format.
READ_DUTY_CYCLE
The READ_DUTY_CYCLE command returns the duty cycle of controller, in percent.
This read-only command has two data bytes and is formatted in Linear_5s_11s format.
READ_POUT
The READ_POUT command is a paged reading of the DC/DC converter output power in Watts. The POUT is calculated
based on the most recent correlated output voltage and current readings.
This command has 2 data bytes and is formatted in Linear_5s_11s format.
