Available integrated circuits can let you program a current limit, but they generally involve microcontrollers or data converters (or both). As an alternative, the circuit of Figure 1 lets you program ...

Not that this happens often, but what do you do when faced with a repair where you don’t know the power source but you do know you have to drive LED backlighting? When faced with this dilemma [Eric ...

I use an old ATX PSU as a bench supply for my projects and needed a simple & cheap adjustable current limiting circuit. I use an old ATX PSU as a bench supply for my projects and needed a simple & ...

Download this article in PDF format. It’s now common to see circuit boards that carry hundreds of amps, especially in intensive data-processing applications, electric vehicles, and ac distribution.

Here at Hackaday we really like to feature projects that push the limits of what’s possible, or ones that feature some new and exciting technology that nobody has ever seen before. So what’s so ...

A previous Idea for Design described a technique for protecting the “pass” transistor in a current-limiting circuit against excessive power dissipation (see “Fault-Protected Current Limiter Keeps Its ...

Constant current limiting circuits are commonplace, but sometimes a constant power limiting function is desired instead. This can be because downstream loads, like DC/DC converters, present a constant ...
