Current Limit Test
Use the following instructions to perform current limit test.
•
Set the input supply voltage VIN to 12.5 V and current limit of 10 A and enable the power supply.
•
Connect the power supply on connector T1 of the EVM.
•
By default, the EVM is configured for 2.23 A current limit.
•
Connect a load of 3
Ω
(20 W) at connector T2 of the EVM.
•
The device limits the current to 2.23 A, turns off the internal MOSFET after reaching the thermal
shutdown temperature (TSD) and auto-retries after a time of t
retry
(512 ms)
shows an example of current limit at 2.23 A on the LM76202-Q1EVM
