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.
This is part one of an article discussing the University of Washington’s nationally ranked FSAE electric car (eCar) and combustible car (cCar). Stay tuned for part two, tomorrow, which will discuss the four unique PCBs used in both the eCar and cCars.
Parallax Inc. is known for developing the Basic Stamp microcontroller development board and educational accessory kits. In addition to developing a user-friendly educational platform to learn about 8-bit microcontrollers and software programming, it created a multicore 32-bit chip called the Propeller.
