ABSTRACT:
A power supply circuit is disclosed herein comprising a load current path for connecting a load which has a switching element. The power supply circuit also includes a current sensor for providing a current measurement signal dependent on a current through the load current path. A drive circuit is also included which provides a clocked drive signal with a number of drive cycles, in each case having an on period and an off period, for the switching element. A temperature sensor arrangement with a temperature sensor is provided for determining an environmental temperature in the area of the temperature sensor, which provides a temperature measurement signal dependent on the environmental temperature. The clocked drive signal is dependent on the current measurement signal and the temperature measurement signal.
