The ROHM Isolated Flyback Converter IC with integrated switching MOSFET. This IC is an optocoupler less isolated flyback converter. It is not necessary to use any optocouplers and feedback circuits by a third winding of transformers, these have been ever required to obtain a stable output voltage in former applications. Furthermore, adoption of the original adapted type technology that controls on time makes the external phase compensation parts unnecessary, reduces a lot of parts number and minimalizes applications, which realizes the designs of isolated power supply application with high reliability.
