Note that this circuit topology and application is new to the world. Voltage Multiplier LED Driver Schematic voltage multiplier led driver circuit schematic The problem with LEDs LEDs are essentially ...

The LED driver uses a CMOS 555 timer since it operated with low voltages and can work for about 190 hours when using a single NiMH battery cell rated at 2000 mAh. The 555 timer drives the transistor ...

In this case, a PIC12F1501. A PIC alone won’t handle a 10 watt LED, so he utilized a CAT4101 constant current LED driver from ON Semi. The PIC performs three tasks in this circuit.

We will look at alternatives to implement analog dimming on conventional LED driver circuits, and a complete solution based on a simple, minimal-external-components architecture will be presented ...

There are two popular methods for dimming LEDs in switch-mode driver circuits: analog and Pulse-Width Modulation (PWM) dimming. Analog Dimming refers to the adjustment of the nominal LED current.

The LED driver circuit is a buck (stepdown) solution and the circuit presented here can operate from most any input voltage source as long as it exceeds the forward voltage of the LEDs to be driven. A ...

In this article, we continue our discussion on the importance of grounding when installing LED lighting equipment. Part 1 of this three-part series focuses on the ground plane of the printed circuit ...

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 ...

[Petteri Aimonen] created an omnidirectional LED safety light to cling to his child’s winter hat in an effort to increase visibility during the dark winter months, but the design is also grea… ...

Seoul Semiconductor, a leading global innovator of LED products and technology, has developed the industry’s smallest 100V / 24W LED driver for Japan ...
