2.1 Power Requirements

When powering the CC2662RQ1-CSU-EVM there are two ways the user can power the board. The user should keep in mind that the recommended operating conditions for the battery range is from 9V to 90V for full functionality.

When powering the board with either option detailed in this section, the BQ device will provide 5V (AVDD) supply to the TPS715-Q1 LDO which will generate the 3.3VDC supply for the CC2662R-Q1device if the power switch (S3) is enabled.

Additionally, the user can place the power switch S3 in the off position and provide an external 3.3V supply to the CC2662R-Q1 device using either the debug connector J10 or the header J12.
