NCL30060BDR2G

The NCL30060BDR2G is a high PF offline single stage LED Driver with high voltage start-up. The switch mode power supply controller intended for low to medium power single stage power factor (PF) corrected LED drivers. It employs a constant on-time control method to ensure near unity power factor across a wide range of input voltages and output power. It can be used for isolated flyback as well as buck topologies. The device offers a suite of robust protection features to ensure safe operation under a range of fault conditions. It is intended for constant voltage (CV) regulated output driver where a DC-DC converter or linear regulator in the second stage controls the current to the LEDs so the output short-circuit protection detector function has been disabled.
