General Description  
Key Specifications  
Input Voltage Range:  
VIN Pin  
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.
