Use the following instructions to perform over current test on the TPS4800Q1EVM:
- Turn ON the power supply and set the power supply output VIN = 48 V, current limit = 20 A.
- Set the Short Circuit Protection (SCP) threshold at 15 A by installing jumper
J8 in 5-6 position and install jumper J7 in 1-2 position to set 1-ms delay.
- Enable the control input (INP).
- Now, load the output to 12 A with electronic load and apply a step of 6 A to
observe the overload behavior of TPS48000-Q1.
- Disconnect the load.
- To perform short-circuit test, uninstall J7 to set shortest SCP delay.
- Now, perform output short to capture the short-circuit behavior of TPS48000-Q1.
