The LED driver IC enables reduction of
power loss during switching and critical-conduction mode allows power factor
correction control using few external components and realizes a power factor of
0.9 or higher.
A variety of control modes can be
achieved by changing the configuration of the externally connected elements.
Examples include buck-boost control, average-current control, peak-current
control and constant-input-power control.
Renesas Electronics' R2A20134 LED driver IC also can be employed in TRIAC dimmer applications
by applying a voltage matched to the TRIAC phase to the feedback pin for constant-current control.
Samples of Renesas Electronics' new LED
driver IC will be available starting in December 2010,
priced at $1 per unit. Mass production is scheduled to begin in March 2011.
The Dutch are known for their love of bicycling, and they’ve also long been early adopters of green-energy and smart-city technologies. So it seems fitting that a town in which painter Vincent van Gogh once lived has given him a very Dutch-like tribute -- a bike path lit by a special smart paint in the style of the artist's “Starry Night” painting.
