STEVAL-ILL013V1
This demonstration board design is complaint
with standard EN61000-3-2 (limits for harmonic
current emissions).
Description
The use of high power LEDs in lighting
applications is becoming increasingly popular due
to rapid improvements in lighting efficiency, longer
life, higher reliability and overall cost
effectiveness. Dimming funtions are more easily
implemented in LEDs, and they are more robust
and offer wider design flexibility compared to
other light sources.
The STEVAL-ILL013V1 demonstration board is
an 80 W offline dimmable LED driver with high
power factor (PF) intended for 350 mA, 700 mA
and 1 A LEDs.
The converter is designed as a constant current
source to achieve the best lighting performance
from the LEDs, and can be used for lighting
applications from low power, low voltage to high
power, high voltage. This allows designers to
cover a wide range of different LED systems
using a single topology.
Additionally, in lighting applications where the
input active power is higher than 25 W and a high
power factor is required, the high PF converter
can be connected as the first stage, before the
modified BUCK converter.
