3.1.3 State Transition (LPM to Active Mode with LPMb Trigger)

Use the following instructions to verify state transition of TPS12130-Q1 with LPMb trigger.

  1. Apply 12 V at the input of the EVM at no-load.
  2. Enable the EN/UVLO to HIGH.
  3. Now, make LPMb from LOW to HIGH to see the state transition from LPM to active mode.
