An over temperature compensation control circuit is coupled to a conversion unit. The over temperature compensation control circuit includes a detection circuit, a temperature control resistor, and a comparison unit. The detection circuit provides a current signal responsive to an input voltage according to a voltage signal responsive to the input voltage of the conversion unit. The temperature control resistor generates a temperature control voltage according to the current signal. The comparison unit compares the temperature control voltage with a reference voltage to generate a control signal. The control signal represents whether a temperature of the conversion unit reaches an over temperature protection point.

Over temperature compensation control circuit

A wall socket includes a socket housing, an output terminal, a power converter circuit and a load detection circuit. The output terminal is arranged at a side of the socket housing and configured to output a DC output voltage. The power converter circuit is arranged in the socket housing and configured to convert an input voltage to the DC output voltage according to a control signal. The load detection circuit is configured to receive an identification signal outputted by an electronic device when the electronic device is connected to the output terminal, and output the control signal according to the identification signal to adjust a voltage level of the DC output voltage.
