To improve efficiency in high-power applications, voltage regulators can be used in parallel to double output current capability—if a means of forcing current sharing is provided. One circuit approach ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...

Decreased system reliability due to overloaded power supplies is a common engineering challenge. In this Q&A-style article submitted by Allied Electronic & Automation, David Norton, technical ...
