hi Jing, thank you for that pdf on optimizing gate drive. my max amps is 4-5, 90% of time my boost is outputting 2-3 amps.
the pdf calcs show my TPS43061 with 5.5v gate drive is very advantageous. knowing that, I can optimize mosfet selection for 5.5v drive.
I'm back onto designing my TPS43061 boost circuit.
