This circuit uses a few standard discrete components to provide a user-settable current-limit function with closed-loop performance. In addition, the limiter function can be turned on and off via an ...

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 ...

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 ...

This current-limiting circuit, shown in this example as part of a small bench power supply, could in principle be used in conjunction with any dual-rail current source. The part of the circuit to the ...

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 & ...

Adding a clamp circuit to the well known current-limiter protects the "pass" transistor from over-currents when load faults occur. Most readers are probably familiar with two-terminal current-limiting ...

Central Semiconductor has created a line novel of zero temperature coefficient current limiting diodes, packaged in DPAK and rated at between 27 and 575mA. Minimum voltages range across 1.5 to 2V – ...

Industrial automation customers can improve their short-circuit protection with a new line of current-limiting, molded-case circuit breakers from Rockwell Automation. The line expands the ...

Littelfuse claims that its CPC1561B Solid State Relay (SSR) is the highest current (1 A, 60 V) normally-open SSR currently available on the market to integrate both current limiting and thermal ...

At first glance, [RobBest]’s constant current source looks old school. The box is somewhat old-fashioned, featuring switches and binding posts. Most importantly, there’s a large analog meter ...
