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 ...

An LED-driver reference design for an LED replacement of 100W incandescent bulbs has been introduced by Power Integrations, writes Richard WIlson. Dubbed DER-322, the circuit is desigend to fit neat ...

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 ...

Circuit Schematic – Driving high brightness LED HB (high-brightness) LEDs require a large amount of current to operate. When driving HB LEDs from a voltage source, you can set the required current ...

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.

Figure 1 shows the LT3496 triple-output LED driver in a buck-mode configuration. Its LED strings reside between PVIN and the 200-m sense resistors, enabling the common-anode connection at PVIN.

The four-channel, two dual buck LED driver circuit has low ripple current and presents a cleaner LED current waveform in contrast to the higher-ripple matrix LED dimmer circuit.

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… ...
