TPS2596EVM: Evaluation Module for TPS2596xx
3. Adjust the VIN1 power supply voltage to a value less than output clamp threshold and turn it ON.
Increase the VIN1 power supply voltage to a value above the clamp threshold. The level of the output
voltage clamp should match with the clamp threshold (based on the respective jumper setting), as
shown in
Table 10 . Figure 5 shows the overvoltage test for jumper setting, J3 = 1-2.
Figure 5. J3 = 1-2, Overvoltage Test (CH1)
4. Adjust the VIN2 power supply voltage to a value less than output lockout limit and turn it ON. Increase
the VIN2 power supply voltage to a value above the lockout threshold. Verify the device turns OFF
when VIN2 is increased beyond overvoltage lockout threshold (based on the respective jumper setting)
and that the FLTb2 RED LED (D5) turns ON.
Figure 6 shows overvoltage test for jumper setting, J12 =
1-2.
