San Jose, Calif. - Fairchild Semiconductor's FDS7066SN3 is the first in a new family of MOSFETs using the company's flip-leaded molded package and SyncFET technology to improve overall efficiency in synchronous dc/dc buck converters by up to 5 percent. Fairchild says the SyncFET chip and included integrated Schottky rectifier offer power and current-handling performance similar to that of a separate MOSFET and Schottky rectifier in half the space when used as the low-side switch. Its 19-amp n-channel PowerTrench MOSFET, rated at 30 volts, has an on-resistance of 4.5 milliohms at 10 Vgs. The price is $2.14 each in 1,000-piece quantities. Delivery is eight weeks ARO.
