With only a few additional components, you can use a highly efficient step-down dc/dc converter to create a constant-current, multiple-channel LED driver. It is relatively easy to drive a ...

A new generation of LED driver ICs, combined with brighter lower-power LEDs, are making it possible to improve the energy efficiency of LCD panel backlighting. The widespread use of notebook computers ...

In the design of power supplies, the desired output voltages can be set manually. This is accomplished in most integrated power supply circuits, as well as switching and linear regulator ICs, with the ...
