BD7J200UEFJ-LB (New)
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 Isolated Power Supply for Industrial Equipment. 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.
This IC uses different production line against series model BD7J200EFJ-LB for the purpose of improving production efficiency. We recommend using this IC for your new development. Electric characteristics noted in Datasheet does not differ between Production Line. In addition, the data of BD7J200EFJ-LB is disclosed for documents and design models unless otherwise specified.
