The PT4115BSOH-B is an LED driver that is packaged in a SOP-8 150mil RoHS compliant surface mount package manufactured by CR-PowTech. It is designed to drive high brightness LEDs up to 6000mA in regulation or pulsed current mode, with a typical flicker-free dimming range of 0.2% – 100%. The LED can be driven from either a DC input voltage of 8V-80V or an AC input of 120V-277V. It also features very low component count and few external components, reducing design complexity and BOM cost. It has built-in output current limit and over temperature protection and requires high-speed switching operations with integrated bootstrap diodes. It offers low voltage dropout performance, high efficiency and low heat dissipation.
