Small-Spaced Dimming Challenges Solved
with LED Lamp Driver IC
With Fairchild’s FL7701 smart non-isolated Buck LED driver with power factor
correction, designers attain efficient dimming solutions that also fit within exist-
ing sockets. Because the need to work reliably in a small space while providing
high efficiency is imperative, the device uses a digital technique that allows it to
automatically detect the AC input voltage condition. A special internal reference
signal is then created, resulting in high power factor correction. The FL7701 will
work from a DC input voltage condition, automatically sensing AC versus DC
input voltage conditions. It also combines high functional density to create the
smallest form factor and allows designers to save up to 20% BOM costs and up
to 60% board space savings.
The LED driver provides energy savings that meet the most stringent worldwide
regulations, such as Energy Star^®. Designers also benefit from the high degree
of integration offered by the FL7701. The result is increased luminary lifespan
to more than five years (current solution only achieves three years.) And reli-
ability is also improved since no electrolytic capacitors for the input, output or
the FL7701 V_DD supply are required.
