Combining two TLx431 regulators together to make a programmable gain current mirror that can be also used for a current loop ...

Circuit and system design requirements often mean compromises. For example, optoisolators are used almost everywhere, but they are highfrequency limited. This simple circuit allows for wider bandwidth ...

The Design Idea in Figure 1 is a precision current mirror used to drive two strings of five white LEDs. To protect the LED string from overcurrent due to an open in one of the strings, you can add two ...
