摘要： A synchronous rectification control circuit is connected with a secondary-side rectification circuit and includes a driving circuit, a dead-time acquisition circuit, and a zero-voltage detection circuit. The driving circuit includes a differentiating circuit, a first comparator, and a capacitor, wherein the differentiating circuit generates a signal to the first comparator and the capacitor functions to charge and discharge to form a cycle. The dead-time acquisition circuit includes a second comparator and a third comparator, wherein the second comparator has a positive input connected to an output of the first comparator of the driving circuit, the second comparator has an output connected to a positive input of the third comparator, and the third comparator has a negative input connected to the output of the first comparator to acquire a dead-time signal. The zero-voltage detection circuit includes a fourth comparator and a totem pole circuit, wherein the fourth comparator has a negative input connected to an input terminal of the driving circuit for detecting a potential present in the input terminal of the driving circuit and the fourth comparator has an output that is connected to the totem pole circuit to supply an output of a signal. With such an arrangement, shorting is prevented from occurring in the secondary-side rectification circuit.

摘要： An electronic apparatus has an electronic component and a pin mount. The electronic component has a working surface and two pins protruding from the working surface and each pin being bent to form an L-shape with a proximal part and a distal part. The pin mount has a flat bottom, a rear, two through holes and two communicating recesses. The through holes are defined through the pin mount in parallel, are formed from the front to the rear and receiving the proximal parts of the pins. The communicating recesses are formed in parallel in the front from the through holes toward the bottom of the pin mount, communicate respectively with the through holes and receiving the distal parts of the pins. The pin mount immobilizes the electronic component to prevent the pins from being detached from the electronic component or the PCB to retain the lifetime of the pins.

摘要： A power factor correction circuit with buck and boost conversions has a rectifying circuit, a buck circuit and a boost circuit. When an input AC voltage of the power factor correction circuit is a relative low voltage, the AC voltage is converted to low level voltage by the buck circuit and then converted to an intermediate voltage with a desired level by the boost circuit. When the input AC voltage is a relative high voltage, the boost circuit is turned off. The input AC voltage is rectified and bucked to the intermediate voltage with a desired level.
