5.3 ON and OFF Control With INP Input

Use the following instructions to verify ON and OFF control of TPS48111-Q1:

  1. Remove the output capacitors of 440 µF from the board.
  2. Disable the pre-charge path by connecting INP_G (TP24) to ground.
  3. Connect the INP (TP6) to ground.
  4. Set the input supply voltage VIN to 48 V and current limit of 10 A.
  5. Enable the power supply.
  6. Now, toggle the INP to HIGH and then LOW to verify the turn-ON and turn-OFF response of PU/PD of TPS48111-Q1.

Figure 5-5 and Figure 5-6 show the turn-ON and turn-OFF responses on the TPS48111Q1EVM Evaluation Board.
