ON Semiconductor – NCL30085, NCL30086 and NCL30088: Power Factor Corrected AC/DC Drivers for LED Lighting

OnSemi_March2015_pg5_featuredOnSemi-logo
The NCL30085, NCL30086 and NCL30088 utilize a power factor corrected current control algorithm which makes them suitable for flyback, buck-boost, and SEPIC topologies. By operating in quasi-resonant mode these devices are able to deliver optimum efficiency across wide line and load levels. The innovative control methodology they employ allows strict current regulation to be achieved (within 2% typically) solely from the primary side.
