Overview

PT4107 Universal High Brightness LED Driver with Improved Current Regulation and EMI Performance GENERAL DESCRIPTION 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 resistor.
A proprietary peak current control method keeps constant average LED currents for wide input and output ranges.
The output current can be programmed from a few milliamps up to more than 1A.
The output current on one LE...
