Hi!
I have problems with MOSFET overheating, while switching resistive load (resistor and LEDs). For driving a MOSFET (I'd tried with two different ones - FDD8444 and NTD3055L104) I'm also using a driver MCP1416. I've made some images with oscilloscope. Can someone explain me what is going one? Why is there a curve on the top of the square signal? Why doesn't MOSFET stays fully opened?
