BD87007FJ-E2

Overview

The BD87007FJ-E2 is a secondary-side synchronous rectification controller designed for flyback converter topologies. It operates within an input voltage range of 2.7 V to 32 V and supports a switching frequency of 50 kHz. The device features a high-voltage drain monitor capable of withstanding up to 120 V, allowing direct monitoring of the primary switch without additional isolation components. It includes built-in thermal shutdown and under-voltage lockout protection mechanisms.

Feature Summary

• Built-in low-power shunt regulator reduces standby power consumption
• Operates in continuous conduction mode without requiring primary-side synchronization signals
• High-voltage tolerance enables direct drain voltage monitoring

Applications

• Secondary-side control in isolated flyback power supplies
• Low standby power consumer electronics adapters
• Industrial equipment power modules

Procurement Notes

Verify the specific suffix E2 against the manufacturer's current datasheet to confirm package type and RoHS compliance status. Confirm that the SOP-J8 package dimensions match your PCB footprint requirements. Ensure the operating temperature range of -40°C to +105°C aligns with your system's thermal design constraints before finalizing procurement.

Selection Notes

Select this component when designing flyback converters that require reduced standby power through integrated secondary-side regulation. It is suitable for applications where minimizing external component count is critical, as it eliminates the need for primary-side synchronization signals during continuous conduction mode operation.

Part Context

This part belongs to ROHM Semiconductor's series of synchronous rectification controllers. It is categorized under Power Management ICs (PMIC) specifically within the Switching Controllers sub-category. The device is intended for general-purpose industrial and consumer applications rather than automotive use.

Replacement Considerations

Public documentation indicates BD87007FJ as an alias or predecessor variant. Verify electrical equivalence and pin compatibility before substitution. No other specific substitute part numbers are confirmed in the provided source material.
