ON Semiconductor NCL30060

High PF Offline Single Stage LED Driver with High Voltage Startup

Overview

Topology Flyback Converter
Input voltage 90-305 V
Output 1 41 V / 0.7 A
IC revision 3

Description

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.
