Hi,
I have attached 2 application notes that are available on the internet for free.
In application note 1, refer to figure 9 and 10 on page number 13.
-> In the dc-dc step down converter, when the high side (control) mosfet is turned OFF, why do we see a large spike and some oscillations if the gate-drain capacitance [Cgd] is low ??
-> In application note 2, on page 9 it is said Fast turn on / off switching gate plateau near middle of gate drive range. Can someone explain this statement in detail and how it helps to have a gate (Miller) plateau at the middle of the driver o/p voltage ??
Thanks.
