摘要： The present invention provides a synchronous switching control circuit for variable switching frequency power converters. It comprises a first circuit to generate a first signal in response to an input synchronous signal of a power converter. A second circuit is coupled to the first circuit to generate a second signal in accordance with the frequency of the first signal. Only when the first signal is operated in a specific frequency range, the synchronous operation is allowed. An oscillation circuit is connected to the first circuit and the second circuit to receive the first signal and the second signal to generate an oscillation signal. The oscillation signal is utilized to enable the switching signal of the power converter. The switching signal is thus synchronized with the input synchronous signal in response to the enable of the second signal. Otherwise, the switching signal will be free running.

摘要： A switching controller for a boost power converter includes a switching-control circuit and a programmable feedback circuit. The programmable feedback circuit is coupled to an output of the boost power converter via a voltage divider. The programmable feedback circuit includes a current source coupled to a switch. On a light-load condition, a power-saving signal turns on the switch. The switch will conduct a programming current supplied by the current source toward the voltage divider. Furthermore, the voltage divider is externally adjustable for programming a determined level of an output voltage of the boost power converter on the light-load condition. Additionally the present invention increases system design flexibility to meet practical power-saving requirements without adding circuitries and increasing cost.

One of the front and rear clip portions has an inner side formed with a hook projection which is spaced from the first edge portion by a first distance. A folder unit has front and back sheet portions adapted to receive documents therebetween, and a hinge portion for hinging together adjacent edge sections of the front and back sheet portions. The hinge portion is clamped in the clip member for retaining the documents in the folder unit. One of the front and back sheet portions is provided with an outwardly projecting retaining piece which has a free retaining edge spaced from the adjacent edge sections by a second distance smaller than the first distance. The hook projection engages the retaining edge when the clip member is provided on the folder unit and is moved in a direction transverse to the adjacent edge sections to permit removal of the documents in the folder unit. The clip member is movable along length of the hinge portion for release from the folder unit.
