5.2 Power Limit Test

Use the following instructions to verify power limit response of TPS1641o on CH1:

  1. Make J3 OPEN.

  2. Set J4 in 1-2 position to set transient blanking time of 5 ms

  3. Set J5 in 3-4 position to set 13.7-W power limit.
  4. Set the input supply voltage VIN to 12 V and current limit of 3 A. Enable the power supply.
  5. Apply load of 1-A at the output.
  6. Now, apply overload to verify the power limiting behavior of TPS16410.

Figure 5-3 shows power limit response of TPS16410 on the TPS1641EVM Evaluation Board.
