Description
The 2008 Wide Range LED Power Module is a high efficiency dc to dc converter which delivers a fixed output current
by varying the output voltage as required to maintain the specified current. Many current output options are available
allowing for use with many types of LEDs and in a variety of applications.
Fixed Current Drive
The fixed output current of the 2008 drivers are designed to supply their rated current to one or more LED junctions.
For example, a 350 mA rated unit will drive up to six Luxeon * I LEDs connected in series. Due to the nature of the
buck regulator, the input voltage must always be higher than the total forward voltage drop of the LED junction(s)
connected in series (2.0V for DC models). Thus, for a series string of six junctions having an average forward drop of
3.5V, the required minimum input voltage will be 21V DC . A standard 24V DC power supply is a good choice for this
application.
Figures 3 through 8 show 700mA (02008B-700) and 1000mA (02008B-1000) units driving various LED circuits. Note
that parallel strings of LEDs can be driven directly with no additional circuitry required to insure current sharing. The
nature of the LEDs themselves will often provide good current sharing if the parallel strings comprise 3 or more
junctions each. Figure 7 shows a 700mA unit driving a Luxeon * V. This could also represent a 350mA unit driving a
Luxeon * I, a 1000mA unit driving Luxeon * III, or a 500mA unit driving a Nichia Jupiter ** .
