PT4207 Universal High Brightness LED Driver 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. The PT4207 integrates a 350mA low side switch. Besides, it provides EXT pin to drive external low side power switch to extend current capacity. The dedicated DIM input can accept either a 0.5V-2.5V analog dim signal or a PWM dim signal. Multi protection is integrated into PT4207 including output open/short circuit protection and soft over temperature protection. Built in soft start greatly reduces the inrush current during start up. PT4207 is available in SOP8 package. FEATURES Support 20VDC-450VDC input r […]
