Product Number: LT1952
Hi,
I need help with the Demo Circuit DC1317A-D.
I used the same schematic, but with a different transformer, which was a customized. And when I was powering it up, I found that the switching of the primary MOSFET was stopped every cycle due to very high inrush current which triggered the overcurrent protection of the IC LT1952-1.
I was wondering whether it is caused by the transformer or there was something that I missed out in the design.
If it was caused by the transformer, what are the specs of the transformer that I should pay attention to when I customize?
Thank you
