Overview
The BD7F200UEFJ-LBE2 is a switching regulator controller with an integrated N-channel MOSFET, designed for isolated buck DC-DC converter applications. It operates within an input voltage range of 8V to 40V and supports a maximum switching frequency of 400kHz. The device delivers up to 5W output power at 12V input and 10W at 24V input, with a typical switch current limit of 2.75A. It functions across an operating temperature range of -40°C to 125°C and utilizes original adapted type ON-time control technology.
Feature Summary
- Eliminates the need for optocouplers or transformer tertiary windings by allowing output voltage setting via external resistors and transformer turns ratio.
- Realizes high-speed load response through original adapted type ON-time control technology, removing the requirement for external phase compensation components.
- Provides highly efficient light load operation via PFM mode while maintaining fixed switching frequency and low output ripple.
Applications
- Isolated Buck DC-DC Converter designs
- Industrial equipment power supplies requiring long-term supply availability
Procurement Notes
Verify the specific suffix LB against official ROHM documentation to confirm package and tape/reel specifications. Ensure compatibility with industrial application requirements regarding long-term supply availability guarantees. Cross-reference the exact part number BD7F200UEFJ-LBE2 with manufacturer datasheets to validate RoHS compliance and operational temperature ranges before procurement.
Selection Notes
Select this component for isolated power designs requiring simplified feedback loops without optocouplers. It is suitable for applications needing fast transient response without external compensation networks. Consider its 400kHz maximum frequency for compact magnetic component design. Verify that the 2.75A current limit meets the peak load demands of the target system.
Part Context
This device belongs to ROHM's series of switching regulators featuring integrated controllers and MOSFETs. It utilizes proprietary ON-time control technology to enhance dynamic performance. The product line targets industrial markets with guaranteed long-term supply availability, ensuring stability for critical infrastructure and manufacturing equipment power systems.
Replacement Considerations
BD7F200UEFJ-LB is listed as a related variant in official documentation. Verify electrical equivalence and pinout compatibility before substitution. No other public substitute part numbers are confirmed for direct replacement.
