General Description

BD7F205EFJ-C is an opto-coupler-less isolated flyback

converter. Feedback circuit by optocouplers or the

auxiliary winding of transformers becomes unnecessary,

contributing to reduction of set parts. Furthermore, the

adoption of original adapted ON-time control technology

enables fast load response. In addition, the various

protection function realizes the designs of isolated power

supply application for high reliability.
