MOSFET provides industry's lowest RDS(ON) in 2x2mm footprint
Saving space and claiming to increase power efficiency in portable electronics, the SiA936EDJ TrenchFET power MOSFET has been announced by Vishay. The manufacturer claims that the dual n-channel MOSFET features the industry's lowest on-resistance RDS(ON) for 20V (12 and 8VGS) devices at 4.5 and 2.5V gate drives in a 2x2mm footprint.
Buck converter requires just 12µA quiescent current
Suitable for telecomms, industrial, avionic and automotive applications, the LTC3637 is a 76V input-capable high efficiency buck converter that delivers up to 1A of continuous output current. Introduced by Linear Technology, it delivers efficiencies as high as 90% and requires just 12µA of quiescent current, maximising battery run time.
VPX power supplies take on harsh environments
Luso Electronics Distribution, the sole UK and Ireland representative for the SynQor range of power supplies and related components, has announced availability of VITA 62* compliant VPX power supplies in 3U- and 6U-high ruggedized packages designed for high performance computing applications in the harsh environmental and demanding electrical conditions of military/aerospace applications as well as communications and industrial industries.
