BD7J101EFJ-LB (Under Development)
Low Power Isolated Flyback Converter IC with Integrated Switching MOSFET

This is the product guarantees long time support in Industrial market. 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 conventional applications. Furthermore, adoption of the original adapter type technology that controls on time makes the external phase compensation parts unnecessary, which realizes the designs of isolated power supply application with drastic reduction of parts number, minimization of application circuits, and high reliability.
