Can you please help us with the customer's inquiry below.
We are developing a DAB converter using two LMG3410R070 in parallel for a DC link of 400V (maximum 450V). In the datasheet, you recommended use decoupling inductors in case of parallel. Do you have more information about these inductors? Value, current capability, saturation, a part number even?
In addition to this. Could parallel direct PINS: IN / FAULT / LPM_N/ RDRV / BBSW / VNEG?
There are problems if LDO5V is connected parallel also?
Do you recommend any special circuit layout to improve the behavior of this device in parallel? Moreover than the regular layout found in the application notes.
In our application 2 isolated sources powered the LMG3410R070. Using the SN6505BDBVT, as appears in the documentation of the device. Control signals come from ISO7831FDW, again following the documentation.
Thank you for your support!
