The PT4115B89E with LED Drivers SOT-89-5 RoHS manufactured by CR-PowTech is a switching step-down DC operating LED driver IC that is designed to drive single-string LED applications efficiently at high output currents. This part is designed to work in a low voltage input range of 5V to 42V, making it an ideal choice for applications with wide input voltage windows. The SOT-89-5 RoHS package is RoHS compliant, offering low thermal interference and reliably operating in a wide temperature range from -40°C to +150°C. In addition, the PT4115B89E includes short-circuit protection, overtemperature protection, and a thermal overload protection. This integrated circuit is ideal for driving single-string LED applications from car battery power sources.
