DC-DC conversion chip boosts efficiency

20 October 2004 Power Electronics / Power Management Infrastructure

International Rectifier has introduced a control and synchronous switching chip set for high-frequency DC-DC converters used for processors in high-end servers and PCs. Other applications include point-of-load (POL) DC-DC conversion. The chip set pair delivers 84,5% efficiency at 90 A in a four-phase 1U VRM outline system switching at 750 kHz per phase and 87% efficiency at 150 A in an eight-phase embedded VRD10.2 design switching at 400 kHz per phase. The first device is the monolithic IRF6691 DirectFETKY, which integrates a Schottky diode and synchronous MOSFET into a single package. While the second device is the IRF6617 DirectFET HEXFET Control MOSFET. Both devices feature IR's patented DirectFET packaging technology that presents a number of design advantages not previously delivered by standard plastic discrete packages.
