2.2 Operation Instructions

  1. Ensure that the USB to I2C Adapter is configured properly using the jumpers mentioned in Section 2.3. This will be the default configurations defined in the tables for most applications.
  2. Configure regulator input supply rails for the expected application using the jumpers mentioned in Section 2.4. Take extra care not to exceed absolute maximum ratings when VSYS supplies BUCK2, BUCK3, or the LDO.
  3. Connect Micro-USB to a PC capable of loading the Camera PMIC GUI.
  4. Connect VSYS to a power supply capable of supporting the application and enable the supply. Typical supply voltage is 12 V. The PMIC will boot automatically as VSYS is applied.
  5. The Buck 1 and Buck 2 regulators will power up automatically once a sufficient VSYS voltage is applied.
  6. Set the SEQ switch (S1) to On to enable the Buck 3 and LDO regulators.
  7. Load the Camera PMIC GUI and ensure the adapter has been recognized by the PC. Refer to TPS650320-Q1 EVM Debugging if the GUI says Hardware not connected.
  8. The GUI will attempt to read all registers and update the register map once the adapter is connected.
