BD7F Series of Isolated Flyback DC / DC Converters

ROHM's BD7F series of DC / DC converters feature an optimized design that eliminates the need for photocouplers and auxiliary winding

Image of Rohm's BD7F Series DC / DC ConvertersConventionally, in order to stabilize the output voltage of isolated power supplies, methods using limited life components, such as optocouplers and / or auxiliary winding, are employed. In contrast, ROHM has developed isolated flyback DC / DC converter controllers that eliminate the need for these types of feedback circuits. The simple, efficient design is ideal for industrial power supplies (FA equipment), power storage systems, and high power inverters.

Features
  • High speed load response achieved through adaptive on-time control
  • Automatic light load mode enables high efficiency throughout the entire load range
  • Supports multi-output configuration for superior cross regulation
  • Eliminates the need for parts that cross the isolation boundary, improving safety
  • Limited-life components are not required which enables long-term operation
