Texas Instruments has expanded its TMS320C2000 microcontroller (MCU) digital power family to help engineers jump start digital-power design. Digital-power designs rely upon a microcontroller that runs power-control algorithms in the digital domain while it controls power in the analog realm. For complete information, visit: www.ti.com/digpwr-pfc-pr-sw.The company grouped its announcement into three sections:1. More than 25 free, modular digital-power software blocks are now available in the controlSUITE software. The free, open-source, and modular digital-power libraries let developers change control techniques in software, so they need not modify or redesign power-related hardware. TI has optimized the software blocks for both the Piccolo C28x core and the control-law accelerator (CLA). For information on the CLA, visit: focus.ti.com/lit/ml/sprb197/sprb197.pdf.2. The new High Voltage PFC Developer’s Kit provides hardware and software needed to quickly implement digital power-factor correction (PFC). The Piccolo F28027 kit (Part no: TMDSHVPFCKIT, $US 249) includes hardware and software for two-phase 300-W interleaved power-factor correction and TI claims engineers can get up and running in under 10 minutes. An isolated JTAG port lets engineers test and debug code without exposing their lab PCs to high voltages.3. Biricha Digital Power Ltd. now offers training that gives engineers a solid foundation in digital-power theory and extensive hands-on lab exercises. The 3-day workshop provides an introduction to digital-power technology, a step-by-step design of a digital power supply (buck topology), and explanations of how to use the Piccolo MCU in digital-power designs. For course information, visit: www.biricha.com/. The 3-day course costs $US 1995.Have you used digital control of power-supply or PFC circuits? –Jon Titus
There is currently much discussion around the term "platform," which may be preceded by the adjectives "mobile," "wearable," "medical," "healthcare," etc. However, regardless of the platform being discussed, they usually have one key aspect in common: They tend to be wireless. So, why is this one aspect so fairly universal? The answer is convenience.
Everyone has a MEMS story. For most of us it’s probably the airbag that saved our lives or the life of a loved one. Perhaps it’s the tire pressure sensor that alerted us about deflation before we were stranded alone on a dark muddy road.
Bioimimicry is not merely a helpful design tool -- it also encourages designers to think not only about how to solve design problems by imitating nature, but how to make the products, materials, and systems they design more ecologically sound and nature-friendly.
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.
