In applications where the readout boards are remotely located, a voltage output current sense amplifier such as the ON Semiconductor NCS21xR series can be converted to a precision current output. The ...

Voltage to current conversion circuits can take on several forms depending on the nature of the load connections. In those cases where the load is single ended, that is one end must be connected to ...

Linear regulators use an internal transistor to control the output voltage. That transistor needs some headroom—you can’t get 5-V output with a 5.01-V input. That headroom is also called dropout.

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 ...

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 ...

Power supply manufacturers sometimes hear from customers with unfortunate dilemmas, such as, “I need to operate the power supply outside its rated voltage range.” Or, “What happens if I exceed my ...

In my previous article on photovoltaic (PV) systems (“The Highs and Lows of Photovoltaic System Calculations” in the July 2012 issue), I went through methods to calculate the changes in voltage due to ...
