Application Information
The BuckBlock TM High Output LED Power Module is a high-efficiency dc to dc converter that delivers a
fixed output current by varying the output voltage as required to maintain the specified current .
Because the forward voltage of LEDs can change based on several environmental factors as well as the
age of the LED, it is important to use this type of driver in an LED system. The higher output currents are
ideal for driving multiple strings of LEDs or high-power LED modules. A fast response current-sensing
circuit permits the unit to be used in applications where flashing 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
When the dimming wires (purple/gray) are left unconnected, the A009 is designed to supply its rated
current to one or more LED junctions. For example, a 2100mA rated unit will drive up to four white
2100mA 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 LEDjunction(s) connected in series.
Thus, for a series string of four junctions having an average forward drop of 3.15V each, the required
minimum input voltage will be 24V DC . A standard 24V DC power supply is a good choice for this
application. Refer to page three for the max Vout/Vin ratings for the various drive currents.
Figures 10 and 11 show a 1400mA and 2100mA unit driving multiple LEDs. 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 provide sufficient current sharing if the parallel strings comprise three or more
junctions each, and are identical in length.
2 - Actual value varies greatly based on input and/or output voltages. Actual values will be smaller in most applications.
3 - Refer to figure 9 for the dimming response.
