11. How to overcome the limits of boost converters
    Frederik Dostal
    Supply Analog Devices ADP1621
    Abstract This article will explain the inherent limitations of the boost topology and how to overcome them. When designing and evaluating boost converters, sometimes the intended output voltage is not realized. Instead, it has a lower value than ...

12. The elegance of a flyback controller without a dedicated isolated feedback path
    Frederik Dostal
    Supply Analog Devices LT8300
    Figure 1 shows the architecture of a conventional isolated flyback converter. These converters can be found frequently in power classes of up to about 60 W. A supply voltage is converted to an output voltage with the help of a primary-side switch ...

13. Measurement circuit features high common-mode rejection
    Chau Tran Moshe Gerstenhaber
    Analogue Design Measurement Analog Devices AD629
    Modern measurement systems often operate with single 5-V power supplies, yet their input signals may have large common-mode voltages that exceed the supply by tens or hundreds of volts. Also, unless the converter is driven differentially, the noise ...

14. Precise voltage regulation with dynamic voltage scaling
    Frederik Dostal
    Supply Analog Devices ADP2147 MAX20480
    Abstract This article discusses the use of dynamic voltage scaling (DVS) to achieve precise voltage regulation. DVS is a process that adjusts the output voltage slightly higher or lower in anticipation of load transients. The article examines how ...

20. Double DAC rate by using mixers as switches
    Randall Carver
    Signal Processing, Filters Analog Devices AD8343 AD9731
    You can effectively double the sample rate of a DAC by interleaving two DACs into a single unit. Updating each DAC on an alternating basis and switching to the appropriate output double the effective throughput of the overall system. It is ...
