The current-doubler rectifier is a popular alternative for the output stage of a buck-derived power converter, which would otherwise use a conventional center-tapped transformer with secondary-side, ...

International Rectifier has introduced the IR3651, a synchronous PWM control IC designed for high performance synchronous DC-DC buck applications with an input voltage range up to 75V. With ...

The most basic diagrams depicting non-isolated DC-DC converters generally show two ideal switches and an energy storage inductor. In early designs, it was quickly realized that one switch could be ...

For the buck-type switch-mode regulators often used in portable equipment, the synchronous rectifier's control circuit has a strong influence on light-load efficiency and noise performance. The key ...

ST has introduced a pair of autonomous secondary-side synchronous-rectification controllers for fly-back converters, suitable for quasi-resonant and continuous-discontinuous conduction fixed frequency ...

Linear Technology has launched a new 65V synchronous buck converter designed to deliver up to 500mA of continuous output current from a 16lead thermally enhanced 3 x 5mm DFN or MSOP package. The ...

After discussing the three transistor high-side buck p-mosfet driver (a recognised circuit and not mine) with some of EW’s sage commenters, I wondered once again if I could design something similar ...

STMicroelectronics has introduced a new family of ultra‑compact synchronous‑rectifier controllers designed to improve efficiency and reduce component count in flyback power converter designs. The ...

EL SEGUNDO, Calif.--(BUSINESS WIRE)--Aug. 17, 2005--International Rectifier, IR(r) (NYSE:IRF), a world leader in power management technology, today introduced the 160A-rated, seven-pin IRF2907ZS-7PPbF ...

Date Announced: 23 Oct 2006 A high-voltage, high-frequency buck regulator control IC for AC-DC offline, non-isolated applications requiring multiple light-emitting diode (LED) circuits or requiring DC ...
