Abstract: A power supply apparatus is provided, and which includes a power conversion circuit, a control chip with soft-start function and a short protection circuit. The power conversion circuit is configured to provide a DC output voltage to a load in response to an output pulse-width-modulation (PWM) signal. The control chip is operated under a DC input voltage, and configured to generate the output PWM signal to control the operation of the power conversion circuit. The short protection circuit is configured to pull-down the level of a soft-start pin of the control chip, so as to substantially/significantly reduce the frequency and duty cycle of the output PWM signal, and then substantially/significantly reduce the current flowing through the shorted load.

Abstract: A power supply apparatus is provided. The provided power supply apparatus has a power backup mechanism, in which a main DC power and a backup DC power are switched by a fast switching circuit composed of a plurality of switch transistors. Since the switching time of each switch transistor is substantially shorter than that of the conventional relay, the backup DC power can be conducted to the input of the multi-output DC-DC converter at a quite-short time even though the main DC power is abnormal. Accordingly, the output of the multi-output DC-DC converter still can continuously and stably supply the operation power required by the load.

Abstract: A charging device and a safety function control circuit and method thereof are provided. When a charging device is not connected to a load, a converted voltage value of a power connection terminal of the charging device is kept to be lower than a safe voltage value so as to maintain a safe mode. The safety function control circuit includes a first control module and a second control module for constant voltage control. The first control module and the second control module perform matching control on a power conversion circuit of the charging device, and in case of a single fault of one of the control modules, the other module is still capable of keeping the converted voltage value to be less than the safe voltage value. Thus, it is ensured that the safe mode stays functional in case of a concurrency of both a single hardware fault and a single firmware fault.
