01. INTRODUCTION An optocoupler, also known as photocoupler or opto-isolator, is a device which can transfer an electrical signal across two galvanically-isolated circuits by way of optical coupling.
Fault protection, for example, from an over voltage or an over current condition can be detected and used to override the normal optocoupler drive. An undervoltage lockout feature could prevent false feedback information during power-up and power down sequences of the power supply.
Unlike transformers or capacitors, which can only transfer AC signals across the isolation barrier, optocouplers can transfer both DC and AC signals alike. This makes them very popular in applications like isolated power supplies or isolated communication interfaces, amongst many others.
Initially developed to address other specific power supply tasks, several control ICs excel in the role as precision optocoupler control and drivers. The basic building blocks necessary for optocoupler feedback control are a precision reference, an error amplifier and a drive stage capable of approximately 20 milliamps.
In order to design a functionally robust and reliable application with optocouplers, it is essential to understand not only the device’s main parameters and parasitic elements, but also their tolerances and variations upon factors like temperature and DC-bias.
