NCL30060: High PF Offline Single Stage LED Driver with High Voltage Startup

The NCL30060 is a 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.
