Isolated IC converter BD7F105EFJ-C

fast

Isolated Type Fly-back Converter IC with Integrated Switching MOSFET for Automotive BD7F105EFJ-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.
