The FSEZ1307 is a
third-generation Primary Side Regulation (PSR) PWM controller combination power
MOSFET providing several features to enhance the performance of low-power
flyback converters. The proprietary TRUECURRENTTM topology, enables precise CC
regulation and simplified circuit design for battery-charger applications.
Using the FSEZ1307 results in a lower cost and lighter charger compared to a
conventional design or a linear transformer. To minimize standby power
consumption, the proprietary green mode provides off-time modulation to
linearly decrease PWM frequency under light-load conditions. Green mode assists
the power supply in meeting power conservation requirements. By using the
FSEZ1307, a charger can be implemented with few external components and
minimized cost. In charger applications, designers have been challenged to
lower standby power and achieve higher efficiency, all while reducing the form
factor of their designs. Currently in these applications, RCC or other IC
solutions are used, with varying degrees of success. With the broadest
portfolio of PSR PWM Controllers in the industry, including the FSEZ1307 PSR with High Voltage (HV) startup and
integrated MOSFET, Fairchild can simplify designs, save board space and meet
today's demands for power savings.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
A group of researchers at the Seoul National University have discovered a way to take material from cigarette butts and turn it into a carbon-based material that’s ideal for storing energy and creating a powerful supercapacitor.
