Abstract
Thermal management of an electronic switch, that provides power to a load, is achieved by monitoring a switch temperature of the electronic switch. When the switch temperature exceeds a first set temperature, the control signal is modified such that an average power dissipated by the electronic switch is reduced. In one embodiment, the control signal is modified by increasing a slew rate of the control signal when the switch temperature exceeds the first set temperature. In another embodiment, a frequency of the control signal is reduced when the switch temperature exceeds the first set temperature.
