Procurement Notes

Verify the specific suffix GE2 corresponds to the SOP-8 tape and reel packaging configuration. Confirm that the component is classified as standard grade and explicitly excluded from automotive equipment applications. Ensure compliance with RoHS directives by checking the official datasheet for environmental certification details before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring integrated high-voltage MOSFETs to reduce external component count. The fixed 65 kHz switching frequency and current mode control are suitable for designs prioritizing transient response stability. Consider the operating temperature range and thermal dissipation requirements for SOP-8 packages when designing for enclosed environments or high ambient temperatures.

Part Context

This part belongs to the BM2P series of AC/DC converters from ROHM Semiconductor. The series focuses on high-efficiency and miniaturization for AC/DC control ICs. These controllers are optimized for reducing power consumption at light loads and incorporate built-in protection circuits and low-noise functions. The BM2P052F variant specifically targets general-purpose AC/DC conversion needs with integrated FET capabilities.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs if considering alternative models within the BM2P series, such as BM2P052, noting potential differences in package type (e.g., DIP-7 vs. SOP-8) and mounting style.
