I am using a TI gate driver LM5106 and I wanted to size the bootstrap capacitor. The application regards a synchronous boost converter. According to pag. 13 I need the \$Qgs\$ charge of the MOSFET that I am trying to switch. I am using the MOSFET IPP075N15N3G.
What IPP075N15N3G datasheet value should I use to size the boot capacitor needed for the gate driver? I am unsure if I should use the gate charge \$Qgs(max)=40nC\$ or the gate charge total \$Qg(max)=93nC\$, reported in page 3 and why.
Thank you so much,
