  • Dealing With Noise Generated By A DC/DC Converter
    each other. Cost reduction efforts have influenced the industry up to a point that IC and converter manufacturers design application-specific products to minimize cost. The most commonly used noise reduction component is a low-pass filter at the output and/or input. Noise in DC/DC converters
  • DC/DC Converter Controller Using a PICmicro Microcontroller
    In many applications, a DC/DC Converter is used to produce a regulated voltage or current, derived from an unregulated power supply, or from a battery. Examples of these applications include battery chargers, electronic air purifiers, emergency exit signs, and distributed power systems. In some
  • Redundancy With Low Voltage, High Output Current DC/DC Converters
    Redundancy using DC/DC converters is necessary when a power system by a DC/DC converter must remain operational in case one of the converters fail. Two or more converters are connected in parallel, but only one supplies the load at any given time while the rest of the converters are in standby mode
  • Optimizing Low Voltage Buck DC/DC Converter Efficiency

  • 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
  • Inductor-Based Step-Up Switching Regulators
    PWM-based converter demands a low output resistance power source or battery.
  • 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
