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 www.onsemi.com LED Drivers. It employs a constant ontime 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 MARKING topologies. The device offers a suite of robust protection features to DIAGRAM ensure safe operation under a range of fault conditions. 8 Version NCL30060B2 is intended for constant voltage (CV) L0060xx regulated output drivers where a DCDC converter or linear regulator ALYW SOIC7 in the second stage controls the current to the LEDs so the output short CASE 751U 1 circuit protection detector function has been disabled. Version NCL30060B3 is intended for applications not requiring Brown Out L0060xx = Specific Device Code protection or output short circuit protection as typical with low xx = A, B, B1, B2, B3, B4 standby operation. The NCL30060B4 removes ontime modulation A = Assembly Location for solutions not needing this feature.
