... GENERAL DESCRIPTION PT4207 is an AC/DC buck constant current driver for high power LED lighting applications. The IC uses a constant off-time control scheme. Both off time and peak LED current is externally programmed. The operating duty cycle can be as wide as 100% and it can power LED load from a 20V-450V power supply. The peak LED current compensation makes sure the LED current is stable within the overall input range ...
