A power conversion circuit is provided. According to the topologies of power conversion circuits and the corresponding control manners of the present disclosure, the output voltage is greatly reduced relative to the input voltage, and thus the function of voltage reduction is achieved. Moreover, a voltage-second product of the time and the voltage across the first output inductor and a voltage-second product of the time and the voltage across the second output inductor are both greatly reduced. Accordingly, the inductance, volume and loss of the first output inductor and the second output inductor are greatly reduced. Therefore, the voltage regulation module may receive the low output voltage outputted by the power conversion circuit, thereby reducing the overall volume of the voltage regulation module and increasing the power conversion density and conversion efficiency of the voltage regulation module.

The present disclosure a program burning device configured to read or write to a program burning interface. The program burning device includes a microprocessor, a programming drive circuit and an overcurrent protection circuit. The microprocessor outputs a first test signal or a second test signal. The programming drive circuit outputs a high driving voltage or a low driving voltage to the program burning interface. After the programming drive circuit outputs the low driving voltage for a preset time, the programming drive circuit outputs the high driving voltage to make the program burning interface form a high impedance. Afterwards, the overcurrent protection circuit receives the first test signal to trigger the overcurrent protection, and then receives the second test signal to trigger the undercurrent protection. If triggering the overcurrent protection and the undercurrent protection are continuously failed over a preset number of times, the microprocessor determines that current protection is failed.
