Fairchild Adds New PowerTrench MOSFETs

Fairchild Semiconductor International (San Jose, CA) announced new additions to its PowerTrench MOSFET line, which provide optimized combined high-side/low-side switch efficiency in synchronous rectifier designs. The FDS6688 and the FDS6694 utilize PowerTrench MOSFET technology and are suitable for notebook, desktop computer and isolated dc/dc converter applications.

The FDS6694 and FDS6688 matched pair chipset provides RDS(on) and Q(G) parameters. The low gate charge, low gate resistance and low on-resistance combined with dramatic die-size reductions are the result of recent advances in PowerTrench MOSFET technology. The low RDS(on) (4.5V) gate drive allows high efficiency to be maintained over a wide operating range. For less critical applications, another new MOSFET, the FDS6682, offers an additional cost-saving option. The new n-channel MOSFETs are offered in space-saving SO-8 packages, rated at 175 degrees C, and are available in tape-and-reel packing.

Pricing is $1.19 for the FDS6688, $0.54 for the FDS6694 and $0.94 for the FDS6682 in 1,000-piece quantities. Samples and production quantities are available now. Delivery is eight weeks ARO.
