LDD-L series

DC-DC Constant Current Step-Down LED driver

LDD-L is DC-DC Constant Current Step-Down LED driver designed in compact size. The entire series could operate from 6~ 36VDC and offer models with different rated current ranging between 300mA and 1500mA. The work efficiency reaches high to 95%, and operates at -40℃~+70℃ under natural air cooling and heat dissipation conditions. Under Built-in EMI filter, LDD-L complies with BS EN/EN55015 and FCC part15 without additional input filter and capacitors. Moreover, the series is equipped with various protections such as Short circuit and Over temperature.

LDD, LDB, LDH series are all DC-DC constant current output LED drivers, LDD is step-down type, LDH is step-up type, and LDB is buck-boost type model. The packaging forms have three forms: pin type, lead type and SMD chip type, which is convenient for various application scenarios. Considering its longevity, high reliability and low cost, Meanwell LDD-L Series serves as an ideally suitable solution for driving illumination LED.
