Designers use step-up-converterICs in battery-powered portableequipment. These chips usually provideone output with a fixed or an adjustablevoltage. Some chips ...

Boost converters provide a higher output voltage from a lower input voltage. Getting the most “boost” possible requires maximizing the operational duty cycle. Boost controllers have a limit on their ...

Buck-Boost DC-DC Converters are versatile power electronic devices that facilitate the conversion of a direct current (DC) input to a DC output that may be either higher or lower than the supply ...

A battery alone may not be capable of supplying complex systems with all the voltage rails necessary to function properly. Applications such as automotive LED drivers, audio amplifiers, and ...

A buck-boost converter maintains a regulated VOUT regardless of whether VIN is above, below, or equal to the output voltage. Ideally, the change from buck to boost and vice versa takes place ...

Find a downloadable version of this story in pdf format at the end of the story. Boost power converters have been widely used for Power Factor Correction (PFC) in ac-dc conversions [1] and for power ...
