ROHM Semiconductor BD7J200 Isolated Flyback Converter IC
ROHM Semiconductor BD7J200 Isolated Flyback Converter IC offers long-term support for industrial use. The ROHM Semiconductor BD7J200 IC has an optocoupler-less isolated flyback converter, eliminating optocouplers and feedback circuits. Using original technology for controlling on-time reduces the need for external phase compensation parts, minimizing components and simplifying designs for high-reliability isolated power supplies.
