Procurement Notes

Verify the specific suffix D1R2G against the manufacturer's latest datasheet to confirm pinout and electrical tolerances. Ensure the source document explicitly lists this part number as active or available. Cross-reference the SOIC-8 package marking code to prevent substitution errors with similar family members that may have different functional configurations.

Selection Notes

Select this controller for high-power DC-to-DC conversion where asynchronous topology is preferred. It is suitable for designs requiring integrated protection features without external components. Consider the 170 kHz frequency for balancing efficiency and passive component size. Verify input voltage ranges match the application requirements before finalizing the design.
