ANALOG TRAINING AND SEMINARS
Analog eLab: Designing with Power Modules: Transient Response, Noise Reduction and Minimizing Capacitors, 11/09/2005. On complex boards, designers are increasingly asked to provide more voltage rails for a wide variety of DSPs, ASICs and FPGAs. Frequently, as many as 6-10 voltages are required, creating power system design challenges for sequencing, EMI suppression and minimizing voltage deviation in the presence of current transients created by high-speed digital circuits. In this eLab we will provide applications solutions for each of these challenges and demonstrate how to minimize the amount of input and output capacitance for DC-DC converters. Techniques for doing simultaneous and sequential sequencing will be demonstrated along with techniques to reduce EMI and how to handle high-speed current transients with a minimum amount of bulk output capacitance. The application examples will be based on TI's new second-generation PTH power modules.
TI Developer Conference: The TI Developer Conference will feature the latest technology in high-performance analog, digital signal processing, microcontrollers and more.
