Fiber Optics in Solar Energy Applications

Posted on 23 July 2012

      They offer insulation protection from high-voltage/current glitches Solar energy has recently become a popular alternative source to meet energy demands around the world due to the fluctuation of oil/coal prices and global warming issues. Oil is a limited and diminishing resource, and because of this, the price surges when demand is high. [...]

History of FET Technology and the Move to NexFET™

Posted on 23 July 2012

      The advantage comes from the low-input gate charge Introduced as a substitute for bipolar transistors, power MOSFETs were used as an electronic switch for power management applications. A power MOSFET has a high input impedance. This means it is a voltage-controlled, unlike the current-controlled, bipolar switch. In other words, a power MOSFET [...]

Optimizing Microcontroller Power Efficiency for Ultra Low Power Designs

Posted on 23 July 2012

      To preserve efficiency, the MCU needs to support multiple operating modes The rise of ultra low power applications has changed how developers must approach power optimization. Devices must support single-cell battery operation, charge/discharge closer to battery thresholds, and be able to control motors and/or high brightness LEDs, all while reducing device form [...]

A Truly Connected Mobile Experience

Posted on 23 July 2012

      The Push for USB OTG The beauty is to charge a battery per the latest USB Battery Charging Specs, using a high efficiency buck topology converter that utilizes a chip inductor for minimized space and cost, but can then run the buck controller in reverse as an effective boost controller requiring no [...]

Simple Light Load Mode Control Optimizes Power Efficiency

Posted on 23 May 2009

      The target is in Point-of-Load Switching Regulators Efficiency ratings for power supplies at full load do not adequately reflect the unit’s power consumption under actual operation conditions. Improved efficiency at all operating points including more typical situations such as very light loads is an important concern in the design of next generation [...]
