5.3 Current Limit Test

Use the following instructions to verify current limit response of TPS16412 on CH2:

  1. Make J10 OPEN.

  2. Set J11 in 1-2 position to set transient blanking time of 5 ms

  3. Set J13 in 3-4 position to set 1-A current limit.
  4. Set the input supply voltage VIN to 24 V and current limit of 2 A. Enable the power supply.
  5. Apply load of 1A at the output.
  6. Now, apply overload to verify the current limiting behavior of TPS16412.

Figure 5-4 shows current limit response of TPS16412 on the TPS1641EVM Evaluation Board.
