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.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
