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 ...

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.

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 ...

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 ...

This 5 volts Switch Mode Power Supply circuit use the IC from National Semiconductor has been producing and designing ICs for use in switch-mode power supplies for many years. The application of these ...

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

“They don’t build ’em like they used to.” There’s plenty of truth to that old saw, especially when a switch-mode power supply from the 1940s still works with its original parts. But when ...

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 ...
