2. A better approach is to use a FET as a constant-current source. The IXTP3N50D2 Dmode FET from IXYS Corp. powers a 5-W white VLED such as the LZI-00NW05 from LEDengin (190 lumens at 1 A); the ...

Tridonic is aiming at high-ceiling industrial led lighting with a 220W harsh environment constant-current driver. ‘LCI 220/500-1400/300 pD NF h28 PRE4’ (trips off the tongue… Ed) works across -40 to ...

The LED current is adjustable via a high ohmic resistor on a dedicated pin with an IC supply voltage ranging between 6 V and 42 V. For safe and reliable operation and to extend the overall LED ...

The AL8400 linear LED driver controller from Diodes Incorporated has been designed to tightly regulate a wide variation of high brightness LED currents via an external transistor. The AL8400 ...

As you know, they need to be current limited which is as easy as applying Ohm’s law to your given set of values. To make things even more even there’s a slew of constant current LED driver ...
