OEM Step-Down LED Driver 30 W
FEATURES
? Single channel LED driver
? Suitable to drive up to 12 InGaN LEDs in series
? Input voltage: 6 V to 48 V
? Output current: typ. 350 mA and 670 mA selectable via
jumper (other output currents customized), 670 mA
predefined
DESCRIPTION
The VLLDU-1-30W single channel LED-driver is a
convenient and flexible solution for operating high-power
LEDs and LED-modules with up to 12 LEDs in series. Due to
its compact dimensions it is possible to accommodate
several drivers in one application to run also sophisticated
LED-modules such as multi array or multi color modules
with a constant current per LED string independent from
forward voltage variations. The output current can be
adjusted by applying an external control signal, either a DC
voltage or a PWM signal, to the “PWM” pin.
PRODUCT GROUP
Product group: LED
Package: PCB, 5 pins
Product series: LED drivers
PARTS TABLE
? Typ. 2 % output current accuracy
