Hi,
I have a question regarding the dead time adjustment (DT1) of the LM5045 controller. I would like to set it at around 1.4 uS but it seems like it has internal limit at around 600ns. Is there anyway to get around that? Thanks.

It is not recommended that you use a resistor larger than 100k on the RD1 and RD2 pins. This will give you the maximum dead time of about 600nS. If you need a longer time delay you could implement an external time delay on the synchronous rectifier gate drive.
