Ladies and gentlemen,
I'm currently using LM26420Q1 in my design and wondering if I can parallel the outputs of the same output voltage to have higher current output to the load. My intention was using 2 separate but the same value of the inductors for both channels. However, using only one resistors network of voltage divider for the Feedback pins on both channels.
- Have anyone done this before
- Is there any issue of paralleling output of both channel without using ORing diodes
- What is the impact to the reliability of the part by doing this
Please advise on this or point me to the right direction how to achieve this task. I know for sure some will ask why don't just use the part with higher out current rating. The answer to that is we've some environmental testing with this part and it's passed so it's very costly to move to different part and repeat the test again. Any input/suggestion is much appreciated. Thank you and have a wonderful Fri all.
