Patent number: 7872879Abstract: A switched mode power converter is provided which includes a transformer (2) having a primary winding (2a) and at least one secondary winding (2b); a primary side active switch device (S1) coupled to the primary winding for selectively applying an input voltage to the primary winding; and a secondary side rectifier circuit including an output filter (6, 12) coupled to the at least one secondary winding (2), and first and second active switch devices (16, 14) coupled between the at least one secondary winding (2b) and the output filter.

Patent number: 7446513Abstract: A dc-to-dc converter has two field effect transistors connected in series between an input terminal and a ground terminal. Adjustment of the dead time when both transistors are off is carried out by providing Kelvin feedback connections directly across the drain and source of one or both of the transistors, so bypassing signal line resistance and inductances.Type: GrantFiled: June 10, 2004Date of Patent: November 4, 2008Assignee: NXP B.V.Inventors: Jan Dikken, Philip Rutter, Kuldeep Kanwar

Patent number: 7199640Abstract: A semiconductor switch comprises two NMOS transistors coupled in an anti-series arrangement, and a gate control circuit coupled to both gates of the NMOS transistors. Both drains of the NMOS transistors are interconnected, and the gate control circuit is coupled to the drains interconnection. The required chip area is halved compared to prior art switches. Pumping the gates to higher voltages may cause a further reduction of the sizes of the NMOS transistors. In addition, advantageously, a large range of input and output voltages can be allowed between the sources of the NMOS transistors, whereby the sources act as input and output respectively of the switch, thus allowing application of the switch in a broad technical field.Type: GrantFiled: September 22, 2003Date of Patent: April 3, 2007Assignee: DXP B.V.Inventors: Guillaume De Cremoux, Insun Van Loo, Jan Dikken, Ferry Nieuwhoff, Yovgos Christoforou, Aykut Kenc, Wilhelmus Johannes Remigius Willemsen

Patent number: 5047657Abstract: An integrated circuit which includes a converter for converting a logic input signal of a first logic type into a logic output signal of a second logic type, for example, from ECL to CMOS level. The converter comprises a buffer, including a controllable load and a driver transistor, and a control circuit. The load is controlled as a function of a control voltage and a reference voltage which are externally applied so that the output signal is substantially equal to the reference voltage if the input signal is substantially equal to the control voltage. In one embodiment the control circuit is a copy of the buffer and receives the control voltage at its input. Its load is controlled by a differential amplifier whose inputs receive the reference voltage and the output voltage of the control circuit. A CMOS-SRAM comprising ECL/CMOS level converters of the above kind communicates with fast ECL circuits and has a low energy consumption.Type: GrantFiled: September 1, 1989Date of Patent: September 10, 1991Assignee: U.S. Philips CorporationInventors: Evert Seevinck, Jan Dikken, Hans-Jurgen O.
