Xitanium driver operating window

LED technology is rapidly evolving. The use of more efficient LEDs
in a next generation means the same light output can be achieved
with lower currents. At the same time, LEDs can be driven at
different currents levels based on the application requirement.
Typically, LED drivers are available in discrete current levels, e. g.
350 mA, 700 or 1050 mA. It is often necessary to replace a driver
when more efficient LEDs or different LED modules become
available.
One of the key features of the Xitanium LED Xtreme SR drivers is
the adjustable output current (AOC) feature, offering flexibility
and future-proof luminaire design. The Xitanium drivers can
operate in a certain
defined by the maximum and minimum voltage and current
0.5
that the driver can deliver. An example of an operating
window is shown on the left. The area indicates the possible
current/voltage combinations. The current selected will depend
on the type
specific LED configuration of the PCB design. The voltage is
the sum of the LEDs used (total Vf string) and
on LED
window of every driver can be found in the driver datasheet.
The output current of these drivers can be set in two ways:
1. SimpleSet: output current can be set using the Philips MultiOne
software and SimpleSet interface.
2. SR interface: output current can be set using the DALI-2-USB
interface.
Warning: the forward voltage V
module must remain within the specified driver operating
window voltage boundaries under all application conditions!
Otherwise, reliable luminaire operation cannot be guaranteed.
