  • Buck-boost Converters
    Buck-boost converters can be used for either step-up or step-down conversions. They can also be used to reverse or invert voltage polarity. With buck-boost converters, the inverting regulator converts a DC input voltage to a DC output voltage that is opposite in polarity to the input. The negative
  • Buck Boost vs. Buck Converter Battery Life for Portable 3.3V Micro Hard Disk Drive Applications
    drive voltage of. 3.3V, an obvious dilemma associated with this application is whether to use a low dropout DC/DC step-down. (buck) converter or a step-down/step-up (buck-boost) converter. A buck converter (Figure 1) provides the most efficient solution with the smallest external components

  • Forward Converters
    Forward, buck, or step-down converters are used to convert a higher DC input voltage to a lower DC output voltage of the same polarity. Forward converters are similar to buck-boost converters, but use a transformer to store energy and provide isolation between the input and output. The difference
  • 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
