Dear Friends,
I'm working wit ha C2000 Launchpad for controlling a buck converter. So there are three wires connected from my circuitry to the launchpad: one ground, one wire carrying sampled inductor current (which is basically a ramp shape voltage between 1.5 and 2 volts) to the ADC module and another wire carrying output PWM command to the IR 2110 MOSFET driver. As soon as I connect my launchpad and start the process, the microcontroller gets so hot, and become unusable (forever). The ADC input waveform seems to be well within the limits. I Also checked the power specs for both microcontroller and the IR2110 MOSFET driver. They say that output from GPIO pins of microcontroller is in range of some milli amps, and the input to the IR2110 is in range of micro-amps. So theoretically, there should not be an overload on output happening for the microcontroller. So I'm wondering what is the problem.
Thank you,
