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.

The series will explore various topologies of Switched Mode Power Supplies. In this first part, the focus is on general voltage converter circuits, including AC to AC and AC to DC converters.

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 ...

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 ...

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 ...

Here, Rich Miron, Applications Engineer at Digi-Key Electronics explores the operation of switch mode power supplies and explores make Vs. buy decision process for power supplies. Miron also ...

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 ...
