2.1.5 I2C Operation

By default, the EVM is set to standalone mode (no I2C operation).

To configure the EVM for I2C operation change following jumper settings:

  • Set JP8
  • Remove JP11
  • Remove JP12

If pull-ups for the I2C interface are not provided by the I2C controller, then add R22/R23.

Note: When changing the output voltage via I2C to voltages higher then 20V, limit the output power for input voltages to be:
  • Higher then 20V to 70W
  • Less then 20V to 45W
