Overvoltage Cut-off Protection Test
Use the following instructions to perform output overvoltage protection test
•
Set the input supply voltage VIN to 36 V and current limit of 10 A and enable the power supply.
•
Connect a load of 28
Ω
(30 W) at connector T2 of the EVM.
•
Observe the waveforms of VIN, VOUT, FLT and IOUT using an oscilloscope.
shows an example of overvoltage cutoff protection on the LM76202-Q1EVM. FLT is pulled-up
from VIN for this test.
