Comprising eight models, the LDC-185 series of AC/DC LED drivers from MicroPower Direct produces a constant-current output ranging from 0.50 A to 5.25 A at corresponding output voltage levels of 25 ...

In some applications, 16 constant-current sinks may be not enough, but you can easily expand the circuit with additional LED drivers. Only one triple-logic inverter is needed to generate the ...

The Circuit The circuit shown in Figure 2 is just a simple tenfold copy/paste of the basic circuit. The value of resistors R11 to R20 is set to 30 kΩ (available in the E24 range of values), while R1 ...

But do you have any idea how those constant current circuits work? If not, then [Giorgos Lazaridis’] guide on LED driving and controlling methods will bring you up to speed in no time.

The A6278 from Allegro Microsystems is an 8-channel constant-current latched LED driver incorporating an open LED detection capability. It is a BiCMOS device which includes an 8-bit CMOS shift ...

Infineon and Nexperia parts All devices have a negative temperature coefficient, which lowers the LED driver current as the internal temperature rises, “thereby protecting and extending the lifetime ...

Block II Avici LED is More Reliable with Technological Innovations Constant Current, Programmable Spectrum The Avici LED line is a breakthrough in horticultural technology. Atlanta, GA, May 05 ...

The LT3743 provides up to 20A of continuous LED current from a nominal 12V input, delivering in excess of 80 Watts. In pulsed LED applications, it can deliver up to 40A of LED current or 160 Watts ...

[Peter] needed to drive a high power LED for his microscope. Rather than pick up a commercial LED driver, he built a simple constant current LED driver and fan control. We’ve featured [Peter’s ...
