  • Programming The AD35 DC/DC Converter
    Referring to Figure 1A, amplifier A1 consists of a low voltage op amp and a high voltage NPN transistor Q1. By grounding the negative output of the AD35, the converter operates as a single positive output DC/ DC from 0 to 200V. A1 through Q1 sets the VO ADJ voltage of AD35. At turn on, the 5VREF
  • DC/DC Converters With Linear Regulators
    is required, the ripple of a switching regulator can be reduced by a linear regulator. The output ripple of a standard DC/DC converter is between 0.5% and 1% of its nominal output voltage. For applications that require a lower output ripple, linear regulators can be used to reduce a converter's output
  • Common-Mode Filters For DC/DC Converters
    common-mode noise, as well as, the output ripple to less than 5mV, which is equivalent to that of a linear regulator ripple. For high-speed analog circuits such as A/D converters, op-amps, S/H, D/A converters, high-speed CMOS, a common-mode filter at the output is highly recommended. A common-mode
  • Output Voltage Adjustment In DC/DC Converters
    signal of the OPAM in order to keep VO constant under any line, load, and temperature variation. It should be understood that a DC/DC converter is a linear system and utilizes negative feedback for control and stability. Also, the output accuracy of the converter depends only on the accuracy
  • Technical Notes for Power Suppies
    Regulated DC voltage is required for semiconductor devices such. as ICs and Transistors to function. Regulated voltage can be generated. from commercial AC lines with an AC to DC power supply or. from DC power source (such as Batteries) with a DC to DC converter. Each type is further classified
  • 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
