Delivering more than 200mA of output current can be a serious challenge for many high-voltage operational amplifiers. But for high voltage applications requiring as much as 1A of current, it is possible to meet this spec by pairing a current buffer with the op amp. What the current buffer brings to this arrangement

Intermediate bus voltages from 24V to 28V (nominal) are commonplace in industrial, aerospace and defense systems, where series-connected batteries may be a backup power source and 12V bus architectures tend to be impractical due to distribution losses. The widening voltage gap between the system bus and the

Life to Return to the Power Supply Industry in 2014

Jonathon Eykyn, IHS Technology

The global market for power supplies crashed in 2012 as economic uncertainties led to low consumer demand and the postponement of large industrial projects. Whilst 2013 bought growth, it was limited to a few markets and the overall market grew by just 2.4%. However, the outlook for the global power supply market
