The PT4107 is a high voltage buck control IC for constant LED current regulation. It allows efficient operation of High Brightness (HB) LEDs from voltage sources ranging from 18VDC up to 450VDC or 110VAC/220VAC. The PT4107 controls an external MOSFET at fixed switching frequency from 25 kHZ to 200 kHZ. The frequency can be programmed using an external resist.
z Proprietary constant-current control. z Wide input range from 18V to 450V or 110VAC/220VAC z Applications from a few mA to more than 1A Output z up to hundreds of LEDs z PWM Low-Frequency Dimming via Enable pin z Linear Dimming via LD pin z Frequency jittering for better EMI performance z Programmable Over temp Protection (OTP) APPLICATION z AC/DC LED Driver applications z RGB Backlighting LED Driver z Signal and Decorative LED lighting TEMPERATURE PACKAGE RANGE ORDERING PART NUMBER SOP-8 -40℃ to 85℃ PT4107ESOH Note: xxxxxX Assembly Factory Code Lot Number TRANSPORT MEDIA Tape and R.
