Abstract: A conversion apparatus with overload control includes a primary conversion circuit, a resonant conversion circuit, and a control unit. The control unit controls a voltage value of a DC power source outputted from the primary conversion circuit according to a current signal of an output current of the resonant conversion circuit. When the control unit realizes that the output current exceeds a rated current according to the current signal, the control unit steps up the voltage value of the DC power source.

Abstract: An electronic device is provided. The electronic device integrates an enable function and an over-temperature protection function (OTP) on the same line, thereby reducing the PCB layout between a microcontroller and a mainboard circuit, and further reducing the circuit complexity and cost. In addition, the negative temperature coefficient (NTC) thermistor in the electronic device is also directly coupled to a circuit pin used for the enable function of the microcontroller to serve as an over-temperature protection application. Therefore, even if the microcontroller fails, the electronic device may still use the hardware circuit structure to automatically achieve the over-temperature protection function.
