Wireless communications took a small leap forward today with the announcement that researchers have created a functional integrated circuit smaller than a grain of salt. The circuit is a broadband ...

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 LED backlight in an LCD panel is the biggest power hog in notebook and tablet applications. As screen resolution and brightness level increase, the input power consumed by the LED backlight ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

Use of buck-boost circuits in switching-regulator ICs. Considerations in level-shift circuit design. Switching regulators with internal level shifting. The magnitude of the negative voltage generated ...
