Isolated Flyback DC/DC Converters

ROHM's isolated flyback DC/DC convertors eliminate the need for photocouplers and auxiliary winding

Image of ROHM's Isolated Flyback DC/DC ConvertersTo stabilize the output voltage of isolated power supplies, methods using a limited-life photocoupler or auxiliary winding with large transformer are typically used for feedback. In contrast, ROHM developed isolated flyback DC/DC converters that eliminate the need for these types of feedback circuits. This simplifies power supply configuration considerably, making them ideal for industrial equipment that demanded advanced safety functions, such as FA equipment, power storage systems, and high-power inverters. The lineup includes two models offered in two different package types.

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 isolations boundary, improving safety
  • Limited-life components not required enables long-term operation
Applications
  • Solar inverters
  • Power storage systems
  • FA inverters
  • Servo amps
