The ROHM optocoupler-less isolated flyback converter with integrated switching MOSFET. 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 isolated power supply for industrial equipment's. 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.
