ADP2108 dc-to-dc converter
The 3 MHz 600-mA ADP2108 dc-to-dc converter balances low operating input voltage capability, low quiescent current and small size offering designers more flexibility in meeting strict system power and PCB area budgets without increasing battery capacity. The converter operates from an input voltage as low as 2.3 V to provide excellent conversion efficiency, transient response and protection. This low operating voltage allows designers to fully use the available battery energy for 2.5-V and 3-V power loads before recharging, which can eliminate the requirement of a more expensive buck-boost regulator in some applications. During light load conditions, the converter switches to a low-quiescent power-save mode for additional battery life savings.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
