Buck-boost converter topologies fit into a wide range of applications. Whether you are charging a battery from a battery, powering a string of LEDs, or running a handheld device from a single cell, ...

Controlling the brightness of LEDs requires a driver that provides a constant, regulated current. To achieve this goal, the driver topology must be able to generate a large enough output voltage to ...

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 ...

Buck-boost converters produce a regulated output voltage either less than or greater than the input voltage. When the input voltage is higher than the output, the converter acts as a buck. When the ...

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 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 (USTC ...

Designing a circuit is a lot easier on paper, where components have well-defined values, or lacking that, at least well-defined tolerances. Unfortunately, even keeping percentage tolerances in mind ...

Analogue Devices has combined switched capacitor and inductive buck conversion in the same topology to reduce the size of step-down dc-dc converters. Called LTC7821, this is “industry first hybrid ...

Analog Devices, Inc., which recently acquired Linear Technology Corporation, has announced LTC3246, a compact, low noise buck-boost charge pump with integrated watchdog timer capable of up to 500mA of ...
