Switching power supplies rely on feedback control loops to ensure that the required voltage and current are maintained under varying load conditions. Design of the feedback control loop influences ...
Fig 1. This basic VCO/waveform generator IC circuit includes a voltage follower loop (formed with IC1) and symmetry feedback loop (IC3) to eliminate an asymmetric duty cycle, which would cause ...
Optocouplers are frequently used in isolated switch-mode power supplies (SMPS) for galvanic separation between the primary and secondary sides as well as from the feedback generator. There are several ...
