Abstract
A power conversion apparatus is disclosed. The power conversion apparatus includes a power transistor, a thermal resistor and a temperature detection circuit. A control terminal of the power transistor receives a control signal. The power transistor converts an input voltage into an output voltage according to the control signal. The thermal resistor has a negative temperature coefficient. The temperature detection circuit generates the control signal and provides a driving current to the control terminal of the power transistor according to the control signal. The temperature detection circuit further generates an over temperature protection signal according to the driving current.
