guys i have a mosfet that i think i have to drive it with higher voltage then 3v - 4 volt and i have to use 3v to 4v power source because its needs to be small and it is a lithium polymer battery. the curcuit is a boost converter i have to generate about 200 volt without load. i searched alot for finding a mosfet that have very low Gth because frequency will be generated with microcontroller but no luck in my country i guess. so i thought maybe there is a way of generating 10v or so just for driving the mosfet and after some research i found out that MOSFETs have capacitance to be charged that at high frequency. and i need to know how much current do i going to need at frequency i want. so how do i calculate it. i found this thread https://forum.allaboutcircuits.com/...urrent-the-gate-of-a-mosfet-will-draw.165357/
someone says that Ig = Qg/t = Qg*F i mean https://pdf.direnc.net/upload/pju7na65-datasheet.pdf this mosfet i have have 16,8 nC so am i suppose to make calculation like this ? if i have 10 kHz so 16,8/10000 ? and this will give me the current ? about 1.6 mA ?
