摘要： A current limit peak regulation circuit, a current limit circuit and a power converter including the current limit peak regulation circuit. The current limit peak regulation circuit provides a current limit threshold to limit a maximum allowable peak current value of a current flowing through a main switch of the power converter and adjusts the current limit threshold to decrease with decrease in a switching frequency of the power converter when the power converter is in a constant voltage mode so as to reduce power dissipation of the power converter in standby mode.

摘要： The present disclosure discloses a DC to DC boost converter, comprising a boosted circuit, a protecting circuit, a detecting circuit, a feedback control circuit, and a feedback circuit. The boosted circuit outputs voltage to the outside through the protecting circuit, the protecting circuit controls the boosted circuit to output voltage to the outside according to the current output from the boosted circuit. The detecting circuit detects the output voltage of the protecting circuit and controls whether the feedback control circuit proceeds the feedback control to the boosted circuit according to the feedback voltage of the feedback circuit or not according to the detected output voltage. The DC to DC boost converter adds the protecting circuit and the detecting circuit, which completely shuts the output down while the output is short, thus achieving short-protecting circuit and reducing power consumption.

摘要： A power supply apparatus with soft-start function is suitable to a load including a voltage stabilizing unit and a load unit coupled in parallel. The power supply apparatus includes a power unit, a soft-start adjusting unit, a current detecting unit and a controlling unit. The power unit generates a power voltage. The soft-start adjusting unit receives the power voltage, a first controlling signal and a second controlling signal, and transforms the power voltage to a soft-start current accordingly to output the soft-start current to the voltage stabilizing unit or output the power voltage to the voltage stabilizing unit. The current detecting unit measures a current of a loop formed between the power unit and the voltage stabilizing unit to generate a current detecting signal. The controlling unit receives the current detecting signal to generate the first controlling signal and second controlling signal.

摘要： A circuit system having a voltage converter having an input path, an output path, and having a plurality of phases, each phase having at least one half-bridge and at least one fuse, each branch of the half-bridge having a respective MOSFET. The circuit system recognizes a defective MOSFET and controls the MOSFETs of the intact phases in such a way that a sufficiently large current trips the fuse connected in series with the defective MOSFET in order to enable an emergency operation of the voltage converter. A method for operating such a circuit system is also described.

摘要： In a control circuit of a switching power supply device, a switching cycle generating unit controls a switching cycle in keeping with a signal of an error voltage detected on a secondary side to stabilize an output voltage at a target value. A load current for overload protection is estimated based on a value produced by integrating a resonant current at an integrator and averaging at an averaging calculation unit. Here, although the switching cycle is correlated to the ratio of input/output voltages, the switching cycle is negatively correlated to the input voltage because the output voltage is controlled so as to be constant. A correction calculating unit uses a signal that decides the switching cycle as information corresponding to the input voltage, which eliminates the need to detect the input voltage.
