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.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
The DDV-IP is a two-wheeled self-balancing robot that can deliver cold beverages to thirsty folks on hot summer days. A wireless RF remote enables manual control of the device beyond the act of self-balancing. All of the features of the DDV-IP result in an effective delivery vehicle while providing entertainment to the user.
Eric Doster of iFixit talks about the most surprising aspect of the Microsoft Surface Pro 3 teardown. In a presentation at Medical Design & Manufacturing Midwest, iFixit gave the Surface Pro 3 a score of one (out of a possible 10) for repairability.
