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 ...

The circuit shown in Figure 1 illustrates one of the most basic versions of the buck-boost voltage regulator. An electrical switch is connected in series with the line input to regulate the circuit.

In many applications, voltages require upward and downward conversion. One example would be if an input voltage range of 6 to 24 V is available, and 12 V would be generated from it. Classical ...

We all know that the reason the electrical system uses alternating current is because it’s easy to step the voltage up and down using a transformer, a feature which just isn’t possible with a DC ...

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 ...

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. The ...

This article looks at how special converters equipped with PassThru mode can be useful when the circuit’s input voltage is too high or too low to power a load. It will give examples of how PassThru ...
