Hi all,
Due to place constraints on the board, we would like to know if it is possible to implement the lm5121 without the high side FET, and consequently run it in asynchronous mode as depicted below:
1. Is it possible to use the lm5121 as an asynchronous boost controller?
2. How should we then connect the HO pin of the gate driver? Floating or pulled down to GND?
3. Do you see any particular drawbacks of this implementation?
I'm looking forward to your reply.
Thanks and best regards,
