BD7J200HFN-LB (Under Development)
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.
