Integrated MOSFET plus driver from Fairchild Semiconductor for ultrabooks

Fairchild Semiconductor has made available integrated MOSFET plus driver device family for high-current, high-frequency, synchronous buck DC-DC applications. The FDMF6708N integrates a driver IC, two power MOSFETs, and a bootstrap Schottky diode into a thermally enhanced, 6x6mm2 PQFN Intel DrMOS v4.0 standard package.

The FDMF6708N is said to provide designers a 50 percent smaller footprint while delivering high-switching frequency and high power density. The device's Zero Cross Detect (ZCD) feature improves light load efficiency for extended battery life. Fairchild says unlike the traditional discrete solution, this device also provides high efficiency at full load using the latest control FET and SyncFET technology as well as clip-bond packaging with lower source inductance.

Available in a PQFN 6x6mm2 package, the FDMF6708N device offers 2.5 percent better efficiency at peak load (15A) and 6 percent better efficiency at full load (30A) than the nearest competitor, according to Fairchild.

Features and Benefits as per Fairchild:
Over 1.0MHz switching frequency capability reduces overall solution size, saving up to 50 percent of board space, and resulting in thinner systems by reducing inductor height
Zero Cross Detect (ZCD) circuitry for improved light load performance
PQFN 6x6mm2 Intel DrMOS v4.0 standard footprint, multi source solution Multi Chip Module (MCM)
2.5 percent better efficiency at peak load (15A) and 6 percent better efficiency at 30A full load, (19Vin, 1Vout, 800KHz) when compared to the nearest competitor resulting in longer battery life

Price: US $1.86 in 1,000 quantity pieces
