Protect your LED lighting circuits Guest columnist Faraz Hasan, marketing and business development manager at Tyco Electronics Circuit Protection Products says that LEDs can require overcurrent ...

How to design LED streetlamp driver circuits In many consumer applications for lighting the cost of existing technology – namely incandescent light bulbs or fluorescent tubes – is so low that LED ...

In the example shown the output stage uses a flyback converter to provide isolation for the driver circuits in the iW3616. The driver chip uses primary-side sensing technology to achieve excellent ...

IRS29831-based LED driver circuits offer smooth, flicker-free dimming with triac-based dimmers. The control IC can be used for LED driver applications up to 25 W and operates directly from a DC input ...

In this case, either minimal or no filtering is needed. The LED Driver Most LED drivers are boost (step-up) converters. Figure 1 shows a schematic circuit diagram of this type of converter.

Suppose we want to drive an LED string with 400 mA. Drivers U1 and U2 (MAX16803) are good for automotive use because they have a high input-voltage range, excellent thermal qualities, and the ...

Cold-cathode fluorescent display backlights are compared/contrasted to LED backlights, and the differences in driver circuits for both are discussed.
