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 - 40°C to + 85°C.

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 10µF
(at least 35V rating) between points R
0
and V
L
.
4. Connect R
0
resistor between points Vin and R
0.
5. Adjust R
0
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 R
0
value by adjusting it CW. See how the output
current rises.

SOLDERING PROFILE
All of the components must be dried prior to assembly as follows:
1.Samples and package type B1 and B5, bulk components - the recommended drying process is to be done at 125°C for 48 hours.
2. For package type T5 - per JEDEC J-STD-033 level 5.
For taped components the recommended drying process is to be done at maximum 70°C.
