Description:

Low-Voltage Secondary-Side Shunt Regulator

Applications

* the MIC4043 normally drives the LED of an optically isolated feedback circuit. The MIC4043 monitors a resistively-divided output voltage and sinks error current through the opto-isolator’s LED (secondary side); the opto-isolator’s transistor (primary side) provides this signal to the controller’s f
