Universal Constant Current Control 1 Channel and 2 Channels The Smallest and Low Profile Constant Current Control 0 - 2.0A, up to 35V, with 170W/in3 Power Density and High Efficiency
FEATURES
* Fully integrated Universal Constant Current Control LED driver * Power density - more than 170W/inch3 * Controlled output current * BGA construction * Temperature range: - 40C to + 85C * No external components required * Output power 60W per channel * 2 totally independant channels * Maximum current 2.0A per channel * Low profile The Universal Constant Current Control is a 1&2 channel driver dedicated for optimum performance to drive Power LED s. 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 - 40C to + 85C.
APPLICATION
* LED lighting * Backlight * Bike lamps * Positioning with LASER LEDs * UV LEDs for ink drying * Infrared LEDs * Headlights and flashlights * Medical instrumentation * General and emergency/alarm lighting * Design and architectural lighting * Interior and runway lights * Outdoor accent lighting * Household appliances

DEMONSTRATION BOARD TEST SET-UP AND OPERATION
1. Connect the DB according to the circuit drawing below without connecting the LED 2. Use DC power supply, with at least capability of 40V; 2A. 3. For applying up to 35V input voltage please add 10F (at least 35V rating) between points R0 and VL. 4. Connect R0 resistor between points Vin and R0. 5. Adjust R0 to full CCW. 6. Connect the LED or equivalent resistor value according to the circuit drawing below. 7. Adjust power supply to a minimum of 1V above the LED voltage*. 8. Increase R0 value by adjusting it CW. See how the output current rises. *note: WD**= (Vin - VL) IL < 1.5W Vin - VL = < 20V **WD = Power Dissipation
