LEDD16_24 Series
Constant current power LED driver - Wide Input - Non-Isolated & Regulated
LED Driver
The LEDD16_24 is a high-efficiency series of step-down converters optimized to
driving high current LEDs. The device operates from an input of 7VDC to 30VDC
and provides an externally adjustable output current up to 1000mA and output
power up to 24 watts. Compact size of DIL16 allows designers to integrate this
driver together with LED module. UL94V-0 grade molded case with high grade
filling material provides excellent fire proof characteristics.
