Overview
The BD7J200UEFJ-LBE2 is an isolated flyback converter IC with an integrated switching MOSFET, designed for optocoupler-less applications. It operates within an input voltage range of 8 V to 80 V and supports a maximum switching frequency of 400 kHz. The device functions reliably across an operating temperature range from -40 °C to +125 °C, with an operating supply current of 2.8 mA. It utilizes adaptive on-time control technology to eliminate the need for external phase compensation components.
Feature Summary
- Eliminates the need for optocouplers or transformer tertiary windings for feedback
- Integrates an N-channel power MOSFET within the controller package
- Employs adaptive on-time control technology for high-speed load response
- Supports fixed switching frequency operation with low output ripple
Applications
- Industrial equipment power supplies
- Isolated DC-DC conversion systems
- Compact power modules requiring reduced component count
Procurement Notes
Verify the specific suffix LBE2 against the manufacturer's official datasheet to confirm packaging details and tape-and-reel specifications. Ensure compatibility with industrial-grade temperature ratings (-40 °C to +125 °C) for your target application environment. Cross-reference the HTSOP-J8 package dimensions with your PCB footprint design to ensure mechanical fit. Confirm RoHS compliance status through the latest product notification documents provided by ROHM Semiconductor.
Selection Notes
Select this component when designing isolated flyback converters that require simplified feedback loops without optocouplers. It is suitable for applications demanding high reliability in industrial environments due to its extended temperature range. Consider the integrated MOSFET capability for space-constrained designs where external switching elements are undesirable. Evaluate the 400 kHz switching frequency against electromagnetic interference requirements and transformer design constraints.
Part Context
This part belongs to the BD7J200UEFJ-LB series of isolated flyback converters manufactured by ROHM Semiconductor. The series is characterized by long-term supply availability guarantees for the industrial market segment. These devices represent a shift towards simplified isolation architectures by removing traditional optical feedback mechanisms while maintaining stable output regulation through proprietary control algorithms.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence carefully if considering alternative isolated flyback controllers with similar input voltage ranges and integrated switch capabilities.
