Fairchild’s PowerTrench® MOSFETs Enable Power Supplies To Meet 80 PLUS Silver Specification
Fairchild Semiconductor announced that it is bringing designers an efficient synchronous rectification MOSFET solution that enables power supplies to meet the 80 PLUS Silver specification. The FDP025N06, FDB024N06, FDP032N08, FDB031N08, FDP047N10, and FDB047N10 60 to 100V MOSFETs are designed using Fairchild’s advanced PowerTrench® process that minimizes on-state resistance, while maintaining what is described as superior switching performance and ruggedness.
According Fairchild, compared to traditional diode solutions that are limited by higher voltage drops during high current conduction modes, these Power Trench MOSFETs with their ultra-low RDS(ON) (1.9mΩ typical, FDP025N06) offer a one-percent improvement in efficiency and meet the 80 PLUS Silver specification for high power applications such as desktop PCs, servers and telecom power. To qualify for this stringent ENERGY STAR® label, computing applications must have power supplies that are 85% at 20% rated output load.
These MOSFETs are part of a comprehensive portfolio of PowerTrench MOSFETs that meet the electrical and thermal performance requirements for today’s electronics. Fairchild’s PowerTrench MOSFET process technology are said to yield exceptionally low values for Miller Charge (QGD), RDS(on), and total gate charge (QG) – enhancements that are said to result in superior switching performance and thermal efficiencies.
These products utilize lead-free (Pb-free) terminals and have been characterized for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020.
The units are priced (each, 2500 pieces) as follows: FDP025N06 – US $3.87; FDB024N06 – $3.97; FDP032N08 – $3.75; FDB031N08 – $3.85; FDP047N10 – $3.75; and FDB047N10 – $4.17, with a delivery of 8 weeks ARO.
