DESCRIPTION
FT833xxx is a high precision primary-side feedback and regulation constant current driver for LED lighting applications. It is designed to work in inductor current discontinuous conduction mode (DCM) and is especially suitable for flyback converter under universal input. Under universal input voltage from 90V to 264V, the system output power...
