Description
High Precision PSR Constant Current LED Driver
--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 for FT833Sxx, FT833Axx, FT833Bxx (SOP8)
and FT833BD (DIP8) is recommended to be no
more than 3W, 6W, 9W, and 12W, respectively.
