350mA Externally Dimmable BoostPuck DC Driver - PCB Mount

The 4015-D-E-350 BoostPuck is a 350mA, 5-28VDC, current regulating driver designed to power one or more high power LEDs from a DC voltage source that is lower (VIN < Vf) than the total forward voltage of all series connected LEDs.

For example, 6 series connected LEDs with a forward voltage of 3.15Vf per LED would have a total forward voltage of 18.9Vf. As the input voltage to the driver must be kept at least 3 volts lower than the total forward voltage of the LEDs, then an input voltage from 5-15VDC would be needed to power the LEDs using this driver.

Due to the nature of a buck regulator, the input voltage to the driver must always be higher than the total forward voltage drop of all series connected LEDs. For example, if you have a series connected string of six LEDs where each LED has an average forward drop of 3.5V, the required minimum input voltage would be 23.5VDC. (3.5 x 6 + 2.5) A standard 24VDC power supply would be a good choice for this application. This information is for reference only. Refer to the manufacturers datasheet for official specifications.
