A high-efficiency buck-boost DC-DC converter was developed by the research team headed by Prof. CHENG Lin from the School of Microelectronics at the University of Science and Technology of China ...

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 ...

Super cap back-up buck-boost converter idles at 60nA Texas Instruments has introduced an IC to mediate between a power rail, a load and a back-up supercapacitor. All the time sufficient voltage is ...

4. The LTC3119 buck-boost converter IC is housed in a thermally enhanced, 28-lead, 4- × 5-mm QFN or TSSOP package. Capacitor Selection. A low-ESR (equivalent series resistance) output capacitor ...

A synchronous buck-boost converter IC from Linear Technology builds on the success of the company’s LTC3440 by extending that device’s input voltage range and by making burst-mode operation ...

Some buck converters will use two FETs. Some will reduce switching frequency based on load. Then there are boost topologies for going from a lower voltage to a higher one and even boost-buck when ...

Buck-boost converters [2] like the TPS63000 regulate the output by switching an inductor with four FETs in a full-bridge configuration (Fig. 1). While these highly integrated devices were designed ...

Switched-capacitor buck-boost circuits, such as National Semiconductor’s LM3355, exist, but most designers think of inductive converters when they hear the term “buck-boost.” Other sophisticated ...

Known as buck converters if they step the input voltage down and boost converters if they step ... such as one that uses an AVR microcontroller to perform the switching for a small circuit, ...
