Application Information
Description
The 3021/3023 Wide Range LED Power Module is a high e ciency dc to dc converter which delivers a xed output
current by varying the output voltage as required to maintain the speci ed current . A fast response current-sensing
circuit permits the unit to be used in applications where ashing or pulsing of the LEDs is required. Several options
are available allowing for use with many types of LEDs and in a variety of operating modes
Fixed Current Drive
The xed output versions of the 3021/3023 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 white 350mA LEDs connected in series at 24V DC . 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 (2.5V for DC models, 4V for AC models). Thus, for a series string of six junctions
having an average forward drop of 3.5V each, the required minimum input voltage will be 23.5V DC . A standard
24V DC power supply is a good choice for this application.
Figures 4 through 6 show 700mA and 1000mA rated units driving multiple LEDs. Note that parallel strings of LEDs
can be driven directly with no additional circuitry required to ensure current sharing. The nature of the LEDs
themselves will provide su cient current sharing if the parallel strings comprise of 3 or more junctions each.
1 - Measured with single emitter; output current drops slightly with additional series junctions to limit maximum power dissipation.
2 - When Vin > 7VDC
3 - Actual value varies greatly based on input and/or output voltages. Value shown is for V in = 24V DC V OUTt =20V DC LED load. Actual values will be smaller in most applications.
