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 – ...

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 ...

Hot-swap circuits are among those measures put in place to protect equipment or personnel, or both. Some power supplies, for example, have built-in and adjustable current limiting (standard in ...

Members can download this article in PDF format. Power systems employ diodes to perform a variety of functions. For example, diodes can protect against damage due to power-source reverse-polarity ...

Current-limiting regulators protect the circuits they feed but don't necessarily protect themselves against excessive dissipation. Here is an Idea For Design with a regulator that does both. A current ...

One of the questions that hobbyists ask over and over is how to select the value of a current limiting resistor for an LED. Usually the seat of the pants response is ...
