Onsemi NCL30001

Description

The NCL30001 is a switch mode power supply controller intended for medium to high power single stage power factor (PF) corrected isolated flyback LED Drivers. It employs a Continuous Conduction Mode (CCM) control technique to ensure near unity power factor across a wide range of input voltages and output power.
