Dear Forum,
I have a problem with the microcontroller 18f4550.
I use its PWM for controlling a driver mosfet (**broken link removed**), and it goes to the boost converter mosfet. The output of the PIC should be 5Volt DC 150kHz 70% Dutycycle. I tested the output (without connecting it to the driver and the boost converter) and it is running well..
I connect the converter with the microcontroller, it worked well and in a short time it became very hot, the driver did not give any output and offcourse the mosfet waas not switching. I dont know the reason for that.
Anyone knows something about this?
