- MTBF > 4.7 MHours P14LD050-24 is a high efficiency step-down converter optimized to drive high current LEDs. The control algorithm allows highly efficient and precise LED current regulation. This driver operates in an dc supply voltage range between 7 V and 30 V and provides an externally adjustable output current of up to 0.5 A and output power up to 14 watts. A compact size allows designer to integrate this driver together with LED module.
