Output Hot-Short Test
Use the following instructions to perform output Hot-Short test
•
Set the input supply voltage VIN to 12.5 V and current limit of 10 A and enable the power supply.
•
Short the output of the device on connector T2, VOUT to GND with a short and thick wire (5cm long
and 4 sq. mm thick).
•
Observe the waveforms of VIN, VOUT, FLT and IIN using an oscilloscope.
shows an example of output hot short on the LM76202-Q1EVM. FLT is pulled-up from VIN for
this test.
