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 ...

DC to DC conversion has come a long way. What was once took an electromechanical vibrator and transformer has been reduced to a PC board the size of a largish postage stamp that can be had for a ...

Texas Instruments' TPS63000 helps extend battery life in smart phones, digital still cameras and other single-cell, Li-ion-powered devices by providing high-efficiency buck-boost power conversion.

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 ...

Linear Technology’s LTC3119 is an efficient, monolithic buck-boost converter that operates with inputs from 2.5 to 18 V (Fig. 1), making it well-suited to operate from one- to four-cell Li-ion ...

Cheap DC-DC converters have been a boon on the hobbyist bench for a while now, but they can wreak havoc with sensitive circuits if you’re not careful. The problem: noise generated by the switch-mode ...
