We are searching a freelancer who can design a LED buck Driver compatible like the
LM3433 (TEXAS instruments)true current source that provides a constant current with constant ripple current regardless of the LED forward voltage [login to view URL] output configuration allows the anodes of multiple LEDs to be tied directly to the ground referenced chassis for maximum heat sink efficiency when a negative input voltage is used.
The LM3433 is at going to NRND condition so no point to use LM3433
After designing the driver we need to integrated with the Arduino due program board for digital control. Arduino program already designed.
