4.4.5.1 Overvoltage Clamp Response
Follow the instructions to verify the Overvoltage clamp response of the device:
1. Set J7 in 1-2 position
2. Set the power supply to 28 V and load of 1 A at the output.
3. Now apply transient input voltage (28 V to 40 V) for 20 ms and verify the Overvoltage clamp response as
