Most modern power-supply control ICs offer built-in overcurrent or short-circuit protection. While some overcurrent-protection schemes are latching, others are nonlatching. When the overcurrent trip ...

The thyristor or silicon-controlled rectifier (SCR) provides a convenient latching mechanism for switching power to a load. However, once the thyristor is triggered into conduction, it supplies no ...

A previous Design Idea outlined a relatively simple circuit in which a momentary pushbutton could be made to function like a latching, mechanical switch. The article generated a good deal of reader ...

This application note provides a practical guideline of TRIAC dimmable LED bulb board design. Passive and active bleeder design guides detail how to maintain latching and holding current without ...
