3.5 Operating the EVM With External MCU or Other Digital Circuit

  1. Onboard analog voltage loop control circuit must be disconnected.
  2. Use J17 header to interface the external MCU or other control circuit.
  3. Follow the power-up and power-down sequence for buck mode or boost mode operation.

Signals required from an MCU or other digital control circuit include UVLO, EN1/EN2, DIR, ISETA or ISETD. Contact TI for info on operating the EVM with the MSP431 Launchpad or C2000 MCU.
