TRAINING AND SEMINARS
2006/2007 Power Supply Design Seminars: This one-day, highly-technical power supply design seminar will give you an array of advanced new power supply concepts, basic design principles and real-world applications examples. This respected series will continue the Unitrode tradition of technical but practical presentations. These seminars will take place at multiple locations world-wide beginning in September.
New Archived Analog eLab Webcast: PCB Layout Techniques for Switching Regulators. This Webcast, aired October 11, was designed to help the systems engineer avoid the pitfalls of poor PCB layout. The discussion demonstrates how to minimize parasitic components when laying out the PCB and how to determine what traces create noise and what traces are susceptible to noise within a switching regulator. Also included is some basic information for laying out a switching regulator and how to place and route the power train and control. With this information, the design engineer should be able to avoid the most common issue when using a switching regulator—noise.
ZigBee™ Training Classes: This hands-on, two-day course in Landshut, Germany and Woodland Hills, California will provide a solid foundation both in ZigBee protocol and in Z-Stack-based product development. Get face-to-face access to expert assistance and answers that address your specific needs. Even if you are currently just evaluating ZigBee, our training course is designed to get you started the right way.
