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 ...

The most common use for a synchronous buck controller is high-efficiency conversion of a positive voltage to a lower positive voltage. But it can also produce a negative voltage from a positive ...

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 ...

Editor’s note: Haifeng Fan is our guest blogger from TI for this blog on the first day of exhibits at APEC 201 A DC/DC converter converts an input voltage source to a desired voltage level. When the ...

4.6 to 5.0V (VPOS) with 0.5% accuracy at up to 500mA from a buck-boost converter-1.4 to -5.4V (VNEG) with 0.5% accuracy at up to 500mA from an inverting buck-boost converter 5.8 to 7.9V (AVDD) with ...

This represents one of the three elementary switching regulator topologies and requires only two switches, an inductor, and input and output capacitors. Besides the boost converter, the other basic ...

Linear Technology Corporation introduces the LTM8045, a 2.8V-18V input, multi-topology DC/DC µModule® (micromodule) converter, with onboard inductor, power switch and DC/DC controller delivering up to ...

Several bias voltages are needed for supplying and operating an LCD panel. In most cases, specialised integrated circuits with several charge-pumps are used to generate the different voltages. As 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 ...
