BD7F200EFJ-LBE2

Overview

The BD7F200EFJ-LBE2 is an isolated flyback switching regulator controller manufactured by ROHM Semiconductor. It integrates a PWM controller and an N-channel MOSFET, eliminating the need for optocouplers or transformer tertiary windings for feedback. The device supports input voltages from 8V to 40V and delivers up to 10W at 24V input. It features adaptive on-time control technology, enabling high-speed load response without external phase compensation components. The unit operates within a temperature range of -40°C to 125°C and utilizes an HTSOP-J8 package.

Feature Summary

• Eliminates the requirement for optocouplers or transformer tertiary windings in isolated power designs
• Utilizes proprietary adaptive on-time control technology to simplify phase compensation design
• Integrates an N-channel MOSFET with built-in protection mechanisms including thermal shutdown and UVLO

Applications

• Industrial equipment power supplies requiring isolation
• Compact isolated DC-DC converter designs
• High-reliability power systems minimizing component count

Procurement Notes

Verify the specific suffix LBE2 against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Ensure compatibility with industrial supply guarantees if long-term availability is required. Cross-reference pinouts with existing designs due to potential revisions in manufacturing lines.

Selection Notes

Select this component when designing isolated flyback converters that require reduced bill-of-materials by removing optocouplers. It is suitable for applications needing fast transient response without complex external compensation networks. Consider the integrated MOSFET ratings and thermal performance for the target power level.

Part Context

This part belongs to ROHM's family of isolated switching regulators designed for industrial markets. It represents a shift towards simplified isolated power architectures by integrating control and power stages while maintaining galvanic isolation through transformer coupling alone.

Replacement Considerations

Check for BD7F200UEFJ-LBE2 as a potential variant. Verify electrical characteristics and pinout compatibility before substitution. Consult official documentation for any product change notices affecting equivalent parts.
