postisolator
A postisolator is a device used in electrical engineering to isolate the output of a circuit from the input, preventing any reverse current from flowing back into the input. This is particularly useful in applications where the input source is sensitive to reverse currents, such as in power supplies, battery chargers, and certain types of amplifiers. Postisolators are commonly used in conjunction with diodes or transistors to achieve this isolation. They are designed to have a low forward voltage drop and a high reverse breakdown voltage, ensuring efficient operation and protection of the input source. Postisolators can be found in various forms, including discrete components and integrated circuits, and are essential for maintaining the integrity and performance of electronic systems.
