Flexible PWM controller fits IBA bill Product News 5/26/2004 Post a comment National Semiconductor positions its LM5033 as the first fully-featured 100-volt DC/DC pulse width modulation (PWM) controller for meeting the needs of modern intermediate bus architectures (IBAs). "The introduction of the intermediate bus is an inflection point in the evolution of distributed power architectures," said Paul Greenland, marketing director for the Power Management group. "Customers expect the next generation of intermediate bus converters to be flexible and efficient without sacri
Modern serial buses demand sophisticated level translation News & Analysis 5/26/2004 Post a comment Electronic design has changed considerably since the days when TTL and 5V CMOS were the dominant standards for logic circuits. The increasing complexity of modern electronic systems has led to lower-voltage logic, which in turn causes incompatible input and output levels for the logic families within a system. It's not unusual, for example, that a digital section operating at 1.8V must communicate with an analog subsection operating at 3.3V. In this article from Planet Analog magazine, a Maxim e
In hot market, only reliable rad-hards need apply News & Analysis 5/24/2004 Post a comment The market for radiation-tolerant FPGAs is heating up as chip vendors roll out new devices intended for military and aerospace applications. But so too is the level of scrutiny they must endure to prove that their parts can work reliably under the harshest conditions.
