It is common for Internet of Things (IoT) devices, industrial sensors, meters, precision, and medical equipment to require both a positive and negative voltage. Often, these voltages must be ...

The lowest-cost way to achieve this goal is to use a 1-quadrant unipolar dc supply (Fig. 1a) outfitted with a polarity reversal relay. However, using a polarity reversal relay brings with it three ...

It is a classic problem when designing with op amps: you need the output to go to zero, but — for most op amps — you can’t quite get down to the supply rail. If your power options are a positive ...

It seems to me that the -5V and -12V lines are pretty much obsolete and just thrown in for compatibility reasons. As a matter of fact the SFX power supply standard drops the -5V entirely but keeps the ...

Low-dropout (LDO) linear regulators have been widely used in noise-sensitive applications for decades. Nevertheless, noise requirements have become tougher to meet as the latest precision sensors, ...

The objective of the circuit is to create a power supply using V-MOSFET technology to support amplifiers while producing 100 Watts power output. Vertical Metal Oxide Semiconductor Field Effect ...

The capacitor auto-discharge module presented in this article is simply a failsafe module that automatically discharges the buffer/filter capacitor in a power supply circuit when its input supply is ...
