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 transformative nature of designing and making things was the overarching, common theme at separate conferences held in Boston by two giants in the PLM space: Autodesk, with its Accelerate 2015, and Siemens’s Industry Analyst Conference 2015.
