FX4040 is a complete adjustable system solution for all Power LED s with high current from 20mA up to 2A. The FX4040 provides a constant current without exceeding the applicable LED voltage to ensure the specified LED load life time. The integrated Universal Constant Current Control provides flexibility of utilizing various battery configurations and chemistries such as NiCd, NiMH, or Li+ and fixed power supplies with input voltage up to 35v. An additional flexibility is provided by using external resistors adjusting the constant output current to various LED configurations. The FX4040 Universal Constant Current Control is available in 9-ports BGA package. In order to satisfy the stringent ambient temperature requirements, the Universal Constant Current Control is designed to handle the industrial temperature range of - 40°C to + 85°C.
