Quiz: How Well Do You Know Adaptive Power Switching?
Is your I/O module overheating? The AD74416H's Adaptive Power Switching (APS) can cut heat dissipation by up to 40% — but how well do you really understand how it works?

LTC6990
Production
The LTC6990 is a precision silicon oscillator with a programmable frequency range of 488Hz to 2MHz. It can be used as a fixed-frequency or voltage-controlled...
Datasheet
LTC6990 on Analog.com
I have a LTC6990 that I'd like to use in a flyback circuit. I'm curious to know if the LTC6990 can directly drive an N-channel MOSFET?
Or will I need a gate driver between the LTC6990 & the MOSFET?
Thanks in advance for any help!
Hi,
Gate capacitance and threshold voltage plays an important role for this desicion.
LTC6990's output swing level can reach to supply voltage 5.5V max. Therefore, mosfet should have much lower threshold voltage to fully open the mosfet.
Having a fast rise time improve performance of the system, when the load capacitors increased, the slew rate of the LTC6990's output will be decreased.
LTSpice has model for LTC6990, you can simulate your sistem or only Mosfet and LTC6990.
Thanks,
Emrecan
