Synchronous Buck Chip Set

Thu, 12/08/2005 - 6:11am

Fairchild Semiconductor introduces a synchronous buck converter chipset designed specifically to optimize efficiency and space in notebooks using the latest IMVP (Intel Mobile Voltage Positioning) specifications. Utilizing Fairchild's PowerTrench® MOSFET technology, the high-side control MOSFET (FDS6298) and the low-side synchronous MOSFET (FDS6299S) form a chip set providing increased current density and improved efficiency in synchronous buck converter applications. In addition, the FDS6299S device's monolithic SyncFET™ technology eliminates the need for an external Schottky diode, resulting in board space savings and reduced assembly costs. This integrated chip set features a very low Qgd or Miller charge for fast switching speeds as well as a Qgd / Qgs ratio of < 1 to limit the potential for cross-conduction losses. In addition to Vcore designs, the FDS6298 and the low RDS(on) FDS6299S offer benefits as a matched pair that are well suited for high current point-of-load (POL) converters in such applications as high-end communications equipment.
