  • 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
  • Methods To Increase The Hold-Up Time Of AC/DC Or DC/DC Converters
    circuit. At turn on, the watchdog circuit sends a 'Power Good” signal to the processor if the supply voltage reaches a predetermined level in a given time internal (T3). This turn on delay (T3) is allowed for the power converter after startup to go through its soft start phase. The soft start time can
  • Application Note: Output Inductor Selection for the AAT115X Series Buck Converter
    , this value guarantees that there is sufficient internal slope compensation which assures stability of the current mode loop for applications requiring greater than 50% duty cycle. With the inductor ripple current set to 40% of the rated current at the maximum input voltage, the converter is guaranteed
  • Inductor-Based Step-Up Switching Regulators
    Inductor-based, step-up switching regulators offer high efficiency, small size and lower cost than isolated switching regulators (DC/DC converters). They are used to amplify (step up) the voltage of a lower voltage source or battery. The inductor stores energy during the on time of the switching
