mosfet capacitance ciss frequency
need help!!! i am driving my MOSFET at 290KHZ. Using IR2110 as my gate driver.
At low frequency, my high side waveform looks good.. it is a square wave. But as the frequency increase, my high side waveform start to look distorted. why is it so? is there a way to solve this problem??
Another problem is, i am using supply voltage of 15V. As i switch my MOSFET at 290KHz, my gate driver gets heated up easily. In less than 10 mins, the IC becomes very hot and i got to off my circuit. Is there any way to reduce the temperature? I cant use a heatsink coz it is a IC chip.
