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.

Application: 12V and 24V lighting systems, household/commercial lighting, suita-

ble for high illumination LED, power limited (battery) lighting system.
