An unstable power supply can cause severe system issues, such as audible noise from the passive components, unexpected jittering in the switching frequency, extreme oscillations on the output voltage ...

To help power supply development, semiconductor companies offer evaluation boards which show a typical application of a power-management IC. This gives design engineers the opportunity to start their ...

Ideally switch-mode power supplies would behave like mathematical models. But since they don’t you need to perform thorough characterization and troubleshooting. Fortunately, modern oscilloscopes are ...

Every automated system that tests electronic circuit boards, modules, or equipment needs one or more DC power supplies. DC supplies provide power to the device under test as well as test stimulus. For ...

The power supply on a computer transforms the alternating current from the wall outlet into a direct current flow that the computer's components can use. Testing the DC voltage output of the power ...

The electronics industry is seeing a move toward higher voltages and currents to deliver sufficient supply and charging power in products ranging from handheld cellphones and tablets to workstations.

The industry’s insatiable need for power in high-performance computing (HPC) is creating problems for test cells, which need to deliver very high currents at very consistent voltage levels through the ...

Before we go forward and run some of the tests that we are going to see hereinafter, let us check a few of the symptoms to understand if those tests are worth doing. We have mentioned some symptoms ...
