Most switch-mode power supplies rely on a PWM (pulse-width-modulated) output that is controlled via voltage feedback. A 555-timer IC can inexpensively perform PWM. The circuit in Figure 1 shows how to ...

Sponsored by Texas Instruments: When going about choosing a power topology, first nail down the required specs and then decide on whether you’re going linear or switch-mode.

Switch-mode power supplies (SMPS) continue to replace linear-regulator types in a host of applications. As the need for more efficient electronics accelerates and as a result of their size, weight ...

So let's discuss the grounding requirements for switch-mode power supplies and offer wiring recommendations that improve availability and reduce problems associated with grounding faults, harmonic ...

Supervisory circuits monitor the power supply and are responsible for power-on, enable-off, and fault protection. A simple hysteretic window comparator, which any power supply might use, monitors the ...

The basic operation of a switch-mode power supply is fairly straightforward, and ATX supplies have very few deviations from the norm. There is a mains rectifier and filter, a pair of high-voltage ...

And, if this is your first introduction to switched-mode power supplies, check out this in-depth look at the similar buck converter circuit to better understand what’s going on behind the scenes ...

An electrical circuit known as a switch-mode power supply (SMPS) provides power while the switching device is not conducting by utilizing high-frequency on- and off-switching circuits in ...

The Rhino line now includes ac/dc switch-mode power supplies encapsulated in an ultracompact, low profile housing.

The proper installation of switch-mode power supplies in control systems is crucial to guarantee 24/7 availability and reduce problems associated with grounding faults, harmonic distortion, and other ...
