  • Output Voltage Ripple in Step-Down and Step-Up Switching Regulators
    Output voltage ripple is always an important performance parameter with DC-DC converters. For inductor-based switching. regulators, several key factors can affect this important parameter, including switching frequency, duty cycle, and. output capacitor value. Step-down and step-up switching
  • Step-Up Switching Regulators
    When a low DC voltage source is used to power circuitry operating at high voltage levels, a step-up (boost) converter can be used. The input (lower voltage) is utilized to charge a passive component, such as a capacitor or inductor by the switching action of a transistor(s). Energy is stored
  • 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
  • DC/DC Converters With Linear Regulators
    regulators, which are switching circuits designed around a PWM energy- storing element, such as an inductor or capacitor, to step up or step down a voltage source. Switching regulators offer higher efficiency than linear regulators, but they also feature higher voltage ripple. When a low ripple
  • How to design boost, SEPIC and flyback regulators with Wide VIN boost power Ics
    data ports, power bank for mobile devices, and tablet docking stations among others. In these applications, input power usually comes from low voltage batteries, solar panels, or other low voltage rails, while a higher output voltage is desired which makes a boost (step-up) DC/DC regulator essential.
  • Ripple and Noise Measurements with DC/DC Switch-Mode Power Supplies
    will summarize the set-up, methodology, and practical measurement guide lines to accu. rately measure input and output voltage ripple (or switching noise). These measurement techniques are. equally suitable to all SMPS DC'DC topologies, as well as charge pump (switched capacitor) reguLators. Other. techniques
  • "VICBricks " Utilize a PRM-VTM Chip-set in a Standard Quarter-Brick Package
    VICBricks, high performance DC-DC converters from Vicor Corp. are only a quarter-inch high and conform to industry-standard quarter-brick footprint and pin outs. VICBricks feature a V I Chip-set, a Pre-Regulator Module (PRM) and a Voltage Transformation Module (VTM), surface mounted on a …
  • Circuit Ideas: Hot-Surface Warning Light Requires no External Power
    to its ceramic sides and on the number of internal junctions in series. This voltage is small when the temperature difference is small. Most circuits require higher operating voltages than a TEG can produce, but a step-up switching regulator with low start-up voltage can boost the TEG output
