NCL30000DR2G

Product Summary

The NCL30000DR2G is a switch mode power supply controller intended for low to medium power single stage power factor (PF) corrected LED Drivers. The NCL30000DR2G is designed to operate in critical conduction mode (CrM) and is suitable for flyback as well as buck topologies. Constant on time CrM operation is particularly suited for isolated flyback LED applications as the control scheme is straightforward and very high efficiency can be achieved even at low power levels. Applications are (1)LED Driver Power Supplies; (2)LED Based Down Lights; (3)Commercial and Residential LED Fixtures; (4)TRIAC Dimmable LED Based PAR Lamps; (5)Power Factor Corrected Constant Voltage Supplies.
