In semiconductors, power losses are the result of inherent impedances in the device. These power losses are converted into heat and cannot be ignored. The same is true for integrated Class-D amplifiers. To remove this heat either the PCB or a top-mounted heatsink attached to the device. If the thermal solution is not properly designed for the required conditions, the audio amplifier can experience reduced performance and potentially trigger the thermal protection.
