Procurement Notes

Verify the specific suffix and tape-and-reel quantity against the official datasheet before ordering. Confirm that the QFN-40 package dimensions match your PCB footprint exactly. Ensure the supplier provides valid RoHS compliance documentation. Check for any recent product change notices that may affect pinout or electrical characteristics. Validate that the operating temperature range meets your system's environmental requirements.

Selection Notes

Select this controller when designing power stages requiring high current capacity and flexible phase configuration. It is suitable for applications where board space is limited due to its integrated bootstrap diodes. Consider the switching frequency range when selecting inductors and capacitors to balance efficiency and transient response. Ensure the input voltage range aligns with your system's power supply rails.
