Cover Story
- Tightened power-efficiency regulations force power supplies to keep up
Both voluntary and mandatory power-regulation standards have forced manufacturers to meet minimum power-efficiency standards or risk losing customers—and, sometimes, markets. New versions of standards and new mandatory federal regulations call for higher efficiencies. These regulations make more sophisticated converter topologies reasonable approaches—even for the lowly wall wart.
Design Features
- As SOCs grow, test-and-measurement instruments move on-chip
Complex ICs are not only absorbing more of the systems around them, but also swallowing the test equipment designers use to bring up, evaluate, and calibrate the chips. - VMM application packages: the next level of productivity
A standardized verification methodology increases output without sacrificing design quality. - USB battery-charger designs meet new industry standards
USB is not just for data transfer any more; there are too many good reasons to use it in such applications as charging handheld-device batteries. New standards address such uses, and new connectors and ICs can make short work of your designs.
