It presumes that every LED in volume-production product has the same forward-voltage drop, and so will see the same current and thus produce consistent output intensity. As a result, the simple ...

The voltage across the LED also presses across the resistors, so these LEDs form four constant-current sources that operate in conjunction with the LEDs. Adjust V R3 such that each LED when on adds ...

In a fashion similar to using stacked Zeners for voltage regulation, this LED circuit cleverly combines voltage reference and voltage indication.

IS32LT3961 integrates Analog & Digital Dimming and spread spectrum to pass CISPER25 EMI Buck LED Driver for Automotive Lighting The 60V 2A IS32LT3961 is a fully integrated constant switching Buck ...

We'll talk about three big ideas: electric potential difference (voltage), electric current, and electric field. Yes, they are all related, and I will show you how with some water and an LED.

[BikerGlen] wanted to spice up his zombie containment unit (see video below) so he designed and 3D printed some very cool looking bar graphs. Apparently, you can get curved bar graph LEDs, but ...

Used for driving high brightness LEDs, the devices’ 6V to 100V input voltage range supports a wide variety of applications, including automotive, industrial and architectural lighting.

Diodes Inc has created a family of two-pin constant current chips that can work at up to 400V. Intended to control strings of LEDs running direct from rectifier mains, and called AL5890, it is ...

In Part 1 of this three-part series, we discussed the importance of a well-engineered PCB ground plane for LED drivers, so the ground plane can be effective in managing disturbance energy generated ...

Linear Technology has announced the LT3909, a high efficiency, constant current LED driver that can drive two strings of up to 10 LEDs at 50mA. To ensure constant brightness, each LED string contains ...
