Don’t Let Your Feedback Loop Fall Flat: Bias Your Optocoupler Right! Optocouplers are critical in switch-mode power supply (SMPS) designs, enabling safe and reliable signal transmission across galvanic isolation boundaries. Their performance hinges on proper biasing and integration within the feedback control loop; misconfiguration can lead to instability, poor transient response, and degraded regulation. This two-part article explores the technical implementation of optocouplers in SMPS. Part 1 covers key operational principles, including…
