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.
George Leopold's talk at last week's Design & Manufacturing Minneapolis helped restore astronaut and engineer Gus Grissom's role in the beginnings of NASA, and outlined how Grissom played a pivotal role in winning the Space Race.
