BD77504FV-E2

BD7J101EFJ-LBE2 is a low power isolated flyback converter IC with integrated switching MOSFET. This product guarantees long time support in the 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 a transformer, this has been ever required to obtain a stable output voltage in conventional applications. Furthermore, the adoption of the original adapter type technology that controls 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. Application includes isolated power supply for industrial equipment.
