  • Dealing With Noise Generated By A DC/DC Converter
    During the conversion process, all DC/DC converters generate unwanted high frequency noise. Over the years designers have used different designs and topologies to minimize and/or eliminate the noise in DC/DC converters. Independent of the design or topology used, cost and performance usually track
  • TSL230 Basic Stamp Experiments
    a current-to-frequency converter. The more light that hits it, the higher the current, and the higher the output frequency. The result is an eight-pin chip, smaller than a dime, which can give us a clock source whose frequency represents a specific intensity of light. Photocells and photo-resistors do
  • Optimizing Low Voltage Buck DC/DC Converter Efficiency
    by the control circuitry quiescent current. In some instances, lnjit load noise requiremenl:s may supercede efficiency requirements. For Ihis type of appli. cation, constant frequency PWM may be necessary for all load conditions.
  • The Evolution of Switched Capacitor Backlight Drivers in Mobile Phones
    of drivers used for LED backlighting: inductive boost converters or charge pumps. To ensure equal brightness of each LED, designers either put all LEDs in series and drive them with a constant current boost converter, or use a switched capacitor charge pump with individual current control for each
  • Synchronization
    multi-frequency harmonics and subharmonics from the power bus (see Figures 6A & 6B for oscillograms of reflected ripple with and without synchronization). The design of the 15W series is based on a current mode PWM in a forward topology configuration. The oscillation frequency is set by a RT-CT
  • Switching power supply design rules
    expensive and more efficient than equivalent linear supplies. Not long ago, efficiency hinged on the converter's switching devices that wasted most of the power budget during relatively low-frequency transitions -- typically 20 to 30 kHz -- between on and off states. Improving efficiency by increasing
  • Sychronous Rectification
    Synchronous rectification (SR) is used in DC/DC converters when low output voltage is less than 5V and high current is needed. Synchronous rectification utilizes power MOSFETs to rectify the output voltage of the power transformer. These MOSFETs are synchronized to the converter frequency
  • Design and Development of Medical Electronic Instrumentation
    to perform volume-conductor experiments with a voltage-to-current converter. and physical models of the body. In Chapter 7 we look at the principles and clinical applications of electrical stimulation. of excitable tissues. Projects include the design of stimulation circuits for implantable. pulse
