The objective is to drive 53 RGB PLCC4 LEDs using a standard Common Anode RGB Controller however we need to limit the current for each color. Each LED has 4 leads, common anode, - Red, -Green, and -Blue. Each LED consumes 15mA and our power supply is 13.5V.

All the LEDs are wired in parallel and having resistors on each LED is NOT an option. We need a BOM / Schematic / Diagram then we can develop and fabricated.

Compétences : Design de circuits, Génie Électrique, Electronique, Microcontrôleur, Mise en Page PCB

en voir plus : plcc4 footprint, tri color led, plcc 2 led, 1210 led, surface mount rgb led, you could you give me the phone number of the driver license over on power, led driver power supply transformer, power led driver schematic, power led driver pcb, battery powered power led driver circuit, power led driver eagle, power led driver battery charger circuit, pic rgb led controller, pic rgb led, pic program rgb led, pic control rgb led, msp430 rgb led, microcontroller rgb led, led controller driver power supply led china, atmel rgb led project

This can be done with relatively simple circuitry. However, I must note that driving all of these LEDs in parallel with no resistors is not advisable. It can be done but any slight variations in the LEDs themselves can Plus
