LM5145: LM5145EVM-HD-20A

Hur
Intellectual 435 points
Part Number: LM5145

Hi,

I am using the LM5145 chip for designing a 30V to 24V dc-dc converter with up to 12A current output requirement. I have the  LM5145EVM-HD-20A and am running some tests for evaluation. I have modified feedback voltage divider resistors to provide 24V output. The maximum current supplied at its output now is around 5.1A at 24V and does not go higher than that. Want to know that does the evm have any internal thermal or power limit? Also is there any other change required in the evm to get a higher output current?  Any help would appreciated.

Thanks,

Hur
