If LED is powered directly form a suitable power source, without an LED Driver circuit, in most cases the LED will pump in more current than it could handle and it eventually get destroyed.

A few months ago I found a led driver module composed of a CN5711 IC, a resistor and a variable resistor. From the CN5711 datasheet: General Description: The CN5711 is a current regulation integrated ...

Circuit Diagram of WS2811 Driver In this circuit, a 5V power supply is used to provide a constant current output of approximately 18.5mA per output pin of the WS2811 driver. This ensures consistent ...

This is the circuit diagram of bipolar LED Driver using microcontroller. Here we use an LED which has a forward voltage drop of 2.2V and hence can be biased using a 5V supply. This Bipolar LED Driver ...

This dimming controlled LED driver circuit is designed using LM3409 P-channel MosFET controller for step-down (buck) current regulators.The LM3409 devices use Constant Off-Time (COFT) control to ...
