Transistors, the tiny switches that flip on and off inside computer chips, have long been the domain of electricity. But scientists are beginning to develop chip components that run on light. Last ...

This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

The TS120 is a multi-function telecom switch integrated circuit that combines a 350 V normally open (1-Form-A) relay with a Darlington transistor optocoupler in a single package. The TS120 is a ...

You can use an LED as a photoelectricsensor. A previousDesign Idea shows that such a switchis highly power-efficient, consumingalmost no power (Reference 1).However, you cannot adjust that ...
