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.
Design collaboration now includes the entire value chain. From suppliers to customers, purchasing to outside experts, the collaborative design team includes internal and external groups. The design process now stretches across the globe in multiple software formats.
A new high-pressure injection-molding technology produces near-net shape parts with 2-inch-thick walls from high-performance materials like PEEK, PAI, and carbon-filled polymers. Parts show no voids, sinks, or porosity, have more consistent mechanical properties, and are stronger.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
