onsemi NCL30060 Offline Single Stage LED Drivers

onsemi NCL30060 Offline Single Stage LED Drivers are 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. onsemi NCL30060 Offline Single Stage LED Drivers offer a suite of robust protection features to ensure safe operation under a range of fault conditions.
