Abstract: An adapter is provided and having a circuit board, primary components and secondary components installed on the circuit board, a shielding plate disposed between the primary components and the secondary components, and a transformer installed on the circuit board. The transformer has a bobbin, an iron core set assembled with the bobbin, at least one movable pin, at least one first winding, and at least one second winding. The movable pin is able to be positioned at an upper position for allowing the iron core set to be assembled with the bobbin or for allowing the first winding and the second winding to be wound onto the winding portion, and the movable pin is able to be positioned at a lower position when the transformer is installed onto the circuit board. Thereby, the adapter can be assembled in an automated process with improved assembly efficiency and high production yields.

Abstract: A transformer includes a bobbin. The bobbin includes a main body, a connection member, and a terminal base. The main body is wound by a coil. Two sides of the connection member are respectively connected to the main body and the terminal base. A plurality of connection terminals of the coil extend to the terminal base through a wire trough of the main body and are connected to pins of the terminal base. The connection member is cut off by automated machining, and the terminal base is mounted on a surface of a housing of the transformer, and no pin is disposed on the housing. Hence, the overall size of the transformer is effectively reduced.

Abstract: A transformer includes a bobbin, a connection pin, a movable pin, a first and a second winding. The bobbin has two side walls between which a winding portion is arranged. A protruding plate extends from one of the side walls, a through hole is defined on the protruding plate, and the connection pin is arranged on the other side wall. The movable pin with a first and second latch portion is inserted in the through hole, the second latch portion is positioned in the through hole, and the first latch portion is arranged away from the protruding plate. The first winding is arranged on the winding portion and connected with the connection pin. The second winding is arranged on the winding portion and connected with the movable pin. Thereby, the transformer could be assembled in an automatic process, with low labor costs, improved assembly efficiency and high production yields.

Abstract: A memory device and a programming method thereof are provided, and the programming method for the memory device includes following steps. During a first period, a first voltage from a common source line is transmitted to first ends of a first memory cell string and a second memory cell string, and second ends of the first and the second memory cell strings are floated. During a second period, the first ends of the first and the second memory cell strings are floated, a second voltage and a third voltage are respectively transmitted to the second ends of the first and the second memory cell strings, and a programming voltage and a plurality of passing voltages are applied, so as to inhibit programming of the first memory cell string and sequentially program a plurality of memory cells in the second memory cell string from a second side of a memory array.

Abstract: An RC delay circuit for providing electrostatic discharge (ESD) protection is described. The circuit employs an NMOS transistor and a PMOS transistor to produce a large effective resistance using a relatively small circuit layout area.
