CODE DESCRIPTION
0x88 Measured input supply voltage.
0x89 Measured input supply current.
0x8B Measured output voltage.
0x8C Measured output current.
0x8D External diode junction temperature. This
is the value used for all temperature related
processing, including IOUT_CAL_GAIN.
0x8E Internal junction temperature. Does not affect
any other commands.
0x95 Measured PWM switching frequency.
0x96 Calculated output power.
0x97 Calculated input power.
0xAC Returns the accuracy of the READ_PIN command
0xD7 Report the maximum measured value of
READ_IOUT since last MFR_CLEAR_PEAKS.
0xDD Maximum measured value of READ_VOUT
since last MFR_CLEAR_PEAKS.
0xDE Maximum measured value of READ_VIN since
last MFR_CLEAR_PEAKS.
0xDF Maximum measured value of external
Temperature (READ_TEMPERATURE_1) since
last MFR_CLEAR_PEAKS.
0xE1 Maximum measured value of READ_IIN
command since last MFR_CLEAR_PEAKS.
0xE4 Measured current used by the LTM4700.
0xF4 Peak internal die temperature since last
MFR_CLEAR_PEAKS.
0xD8 ADC telemetry parameter selected for repeated
fast ADC read back.
