BOOSTXL-BUCKCONV: How to do data conversion for IL_FB, Vout_FB and Vin_FB with f284009c on simulink

Other Parts Discussed in Thread: TIDM-DC-DC-BUCK, C2000WARE


I would like to implement a simulink code into the the f280049c but I need to do the proper data conversion from the 4095 adc count for each feedback measurement. I know that a conversion is realized in the lab1 example described in the technical document:

Can somebody describe me the conversion necessary (scaling or others) to obtain the values displayed in real time (output voltage, inductor current and input voltage) when lab1 program is implemented. The goal is to replicate this conversion on a simulink program implemented in the card

  • The input voltage scaling allows for sampling up to 13.3V on Vin.

    You can find the derivation in the TIDM-DC-DC-BUCK_Calculations.xlsx spreadsheet from the SDK: ~\C2000Ware_DigitalPower_SDK_XXXX\solutions\tidm_dc_dc_buck\hardware\
