ROHM Flyback Converter for Isolated Flyback DC-DC Converter

This product guarantees long time supply availability in the industrial instrumentation market. BD7F100EFJ-LB is an optocoupler-less Isolated Flyback Converter. An optocoupler or the tertiary winding feedback circuit which was needed to obtain a stable output voltage isolated by a transformer in the conventional application becomes unnecessary, thus, the number of parts is reduced drastically, producing a small-sized and high-reliability application isolated type power supply.

• No need for an optocoupler or a transformer tertiary winding
• Uses Original Adapted Type ON-Time Control Technology
• High-speed load response is realized and external phase compensation parts are unnecessary
• Fixed switching frequency and low output ripple
• Highly efficient light load mode available (PFM operation)
• Shutdown / Enable Control
• Built-in N-Channel MOSFET
• Soft start function
• Output load compensation function
