LM74700DDFEVM: 5A limitation

Part Number: LM74700DDFEVM

Hi Team,

Customer want to check for the current limitation 5A with our EVM, but the MOSFET we are using on EVM seems can handle 12A.

Customer would like to know where is the limitation came from and also where to modify if they want to increase current capability, thanks!


  • HI Andrew,

     The reason to specify it as 5A is that the board has been tested only upto 5A. The EVM and the FET used can handle 12A of current. One thing that customer needs to keep in mind is the power dissipation in the FET at higher load currents. If needed, customer can populate the parallel FET , Q2 and test the EVM.
