摘要： A power control device includes: an output voltage controller configured to control an output voltage based on a feedback voltage corresponding to the output voltage; and an overvoltage protector configured to continue or stop the operation of the output voltage controller based on a first detection result of whether the output voltage has exceeded an output voltage threshold value and a second detection result of whether the feedback voltage has fallen to or below a feedback voltage threshold value.

摘要： A short-circuit protection apparatus includes a first detection branch, a second detection branch, and a controller. The first detection branch includes a first sampling resistor and a first sampling capacitor that is connected in parallel to the first sampling resistor. A difference between an absolute value of a second sampling voltage and an absolute value of a first sampling voltage is a first difference. The controller obtains a comparison result between an absolute value of a first sampling voltage at two terminals of the first sampling resistor and an absolute value of a second sampling voltage at two terminals of the second sampling resistor, and if a difference between the absolute value of the second sampling voltage and the absolute value of the first sampling voltage is a second difference and the second difference is less than the first difference, controls the target circuit to stop working.

摘要： A power supply comprises voltage regulation circuitry, a load-share controller, and overcurrent protection circuitry. The voltage regulation circuitry is configured to output a regulated voltage. The load-share controller is configured to control the voltage regulation circuitry to adjust the regulated voltage responsive to a load-share voltage signal (LSV) that indicates an amount of load current being delivered to a load. The overcurrent protection circuitry is configured to selectively couple the regulated voltage to the load. When the load current exceeds a threshold current, the overcurrent protection circuitry is configured to decouple the regulated voltage from the load. While the regulated voltage is decoupled from the load, and when the LSV signal indicates that load current is being delivered to the load by a different power supply, the overcurrent protection circuitry is configured to recouple the regulated voltage to the load.

摘要： An isolated switched-mode power converter converts power from an input source into power for an output load. Power switches within a primary-side power stage control the amount of power input to the power converter and, ultimately, provided to the output load. A digital controller on the secondary side of the power converter generates signals to control the power switches. This controller also senses a rectified voltage on the secondary side of the power converter and uses this sensed voltage to detect fault conditions of the primary side. For example, the sensed rectified voltage is used to detect undervoltage or overvoltage conditions of the input power source of the power converter, or faulty power switches within the primary-side power stage.
