onsemi NCL30060B3DR2G, Power Factor Controller, 60 kHz, 13.75 V 7-Pin, SOIC

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.
