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

How much LEDs in a series? What power source voltage level (or limits min\max)? PCB size limitation? Is it case have a heatsink for power source or only for LED itself? As a sample, XLSemi instead TI is OK for you?
